Alberto Jiménez Obituary

How lucky we are to have something that makes saying goodbye so hard" -A.A. Milne Alberto Jimenez died on August 5, 2018, in San Luis Obispo at the age of 74 and left behind a legacy of love and memories for all who were lucky enough to be loved by him. Born in Moron, Cuba in 1944, Al was raised by his loving parents until Castro took over Cuba. His parents sent him to the USA through an underground exodus program for Cuban minors called Pedro Pan. Al arrived in the U.S. at age 17 alone with one suitcase, no knowledge of the English language, and a fierce determination to succeed. He finished high school, then went on to college with a few other Pedro Pan teens in Wichita, Kansas. There he fell in love with his beloved Judy. They married in 1965 and Judy quickly learned to speak Spanish and cook Cuban food for her favorite guy. In 1967 he proudly became a naturalized U.S. citizen. By 1976, he and Judy had four wonderful daughters and Al had a PhD in Electrical Engineering. After 15 years with IBM, Al took his family to Silicon Valley in 1983 and was involved in a few very exciting start-ups due to his highly respected software programming abilities. Al was also an early bicycle commuter and marathoner. He rode his bike to work throughout his life whether it was a 2 mile or 11 mile commute each way. Al and Judy retired to San Luis Obispo to get out of the busy Bay Area. After a few years of retirement, Al realized that retirement was not for him; he was too smart to not share his knowledge with others. He began to teach in the Math Department at Cal Poly, and ended up with a second career. He taught everything from Calculus to Numerical Analysis for 12 years until retiring once again in 2013. Even after that, he still competed in an online coding and mathematics competition with IEEE every year. During this time, Al also volunteered countless hours with the Assistance League of SLO County helping the League immensely by creating an online management website to facilitate scheduling and databases for their main philanthropic program, Operation School Bell. Al's gifts were so much more than his intelligence and programming abilities. He was a beloved husband of 53 years to Judy, a loving and engaged father to his four daughters and their husbands, and an amazing Grampy/Grampers to his 5 grandchildren. As DaD, he and Judy raised their daughters to be smart, strong and independent adults with love and humor. As Grampy, he has done the same. His grandchildren have grown up with his love, and his goofy "Grampyisms." Their fondest memories are of building a treehouse in Grampy's treasured Avocado Tree and then sleeping up there with him, playing around with music and bongos, and "Froggin'" in his old green Jeep to Cal Poly for Grampy's special "Drive through Petting Zoo." Al lived a full life spending time doing activities he loved. Besides sitting in his FBC (Favorite Blue Chair) to work on his computers, he also loved to drive all over the country with Judy in their small motorhome visiting National Parks and family and friends. Al was a passionate amateur photographer; He always had one of his numerous cameras with him to take beautiful photos of the landscape and of his loved ones. His photos take us on journeys to the National Parks and the California Coastline, as well as the warm Beaches of Florida and the Caribbean Islands. These photographic archives of their travels and our family could fill up a Smithsonian. Grampy-DaD-Al is survived by his beloved wife, Judy; his four daughters and their husbands: Tres Jimenez and Jack Allen of Oakland, Lisa and Tim Jouet of SLO, Susie and Ben Lerner of SLO, and Ani and Monico Casillas of Santa Barbara. He leaves behind his 5 treasured grandchildren: Olive Fontaine (23), Isaac Lerner (17), Eden Lerner (14), Nico Casillas (14) and Kiki Jouet (12). The immediate family is planning a small private ceremony. In lieu of flowers, we ask that you consider a donation in Al's name to the Assistance League of SLO County.

I can describe the last year of Al's activities at IBM.
His activities lead to major innovations, which even today are used in nearly all microelectronic
applications. Klaus D Beyer

I just received a reminder that Al passed away a year ago on August 5th. I still cannot believe that he has left us. I guess God has some sort of finite element (math) calculations that he needed Al for.

I sure hope that God understands Spanish. Why is that you ask? Well, when I worked in Fishkill NY, Al's office was a few doors down the hall from mine. I'd be walking past Al's office and I'd hear him talking to himself in Spanish. I'd put the brakes on and ask Al, What the heck is going on. Al would say something like I'm doing math. SAY WHAT? He further explained that he does all his math in Spanish (I believe that it was has native language). When he got to the answer, he converted the answer to English. It was simpler for him. WHO'D A DUNK IT? That's how efficient Al was. Always trying to optimize something.

It's been approx. 40+ (maybe) years since I learned the above from Al and it still brings a BIG smile to me whenever I think about it. Al I miss you.

Today the lightbulb just went on in my old brain. Al passed away a day before my wedding anniversary. So while my memory may fade, I'll should always remember Al.

Al JIMENEZ was my manager at IBM. I admired him for his superb technical leadership and for his athletic enthusiasm as a marathon runner. Ultimately,his initial guidance led to a major discovery used today in the semiconductor industry.

Alberto Jimenez: A Professional Remembrance

ASTAP! ASTAP! ASTAP (Automatic Statistical Transient Analysis Program)! This circuit analysis program was a major accomplishment of Al Jimenez during his career at IBM. Along with a team of several other engineers and mathematicians, he (and other members of the team) received several significant awards including a corporate award.

The ASTAP program was quite innovative. It created a language for the circuit designers in IBM to use to simulate their designs for the Integrated Circuits for IBM's next generation of computers before committing them to hardware. It then translated that language into Fortran code to fill the sparse matrices of the unique Tableau formulation which were them solved using advanced numerical methods. Al was responsible for the development of the code. William T. Weeks was responsible for the numerical solution of the nonlinear equations. Together they were a formable team. Al developed a number of innovative techniques to maximize the resources of the IBM computers to efficiently and effectively handle the solution of the hundreds of equations that had to be solved thousands of times for a single analysis of an integrated circuit.

After its release, it became the company-wide standard for insuring the design of integrated circuits. Subsequent releases improved the efficiency and effectiveness of the ASTAP program. New challenges from the circuit designers using the program provided new opportunities for innovative updates to the programs such as lossless transmission lines, statistical criteria for Normality, automatic time-cusps, single sided linearization, etc.

About this time, Al departed the ASTAP Development Team to study for his doctorate under the direction of Steven Director in Florida. During that time, he developed another circuit analysis program call IMAC (Interactive Modular Analysis of Circuits that for certain applications was more efficient than ASTAP, and was used by some circuit designers, but it did not receive the necessary resources to become the new standard within IBM. The problem was that there were three circuit analysis programs within a single department: ASTAP, IMAC and ICD.

Al returned to IBM in Fishkill after earning his doctorate to become the manager of the ASTAP team (including me). Because of his great work ethic, he was soon promoted to the staff of a high-level manager. Soon after that, I lost track of him.

In summary, I admired Alberto Jimenez for his knowledge, foresight, and his focus on the immediate and future goals of circuit analysis. Since I documented the individual programs that comprise ASTAP, I became an admirer of his innovative techniques to efficiently maximize the use of the resources of the computer to solve significant problems.

If William T. Weeks were still with us, I am sure that he would add profusely to the above recollections.

I learned yesterday of Al's passing. I was (and still am) in shock, as I was planning on seeing him again after approx. 35 years of absences, sometime this month. I just cannot believe that he is gone. What a loss.


I worked for Al in East Fishkill N.Y. Computer Aided Circuit Analysis. He was a wonderful manager as well as a wonderful person to be around. I remember all the runs/races that we would do. Of course Al was always way up in front of me.


Under Al's management, I was coached and encouraged by him to not let unexpected program crashes discourage me from pushing the envelope. Al, I owe my career to you. Rest in peace.

Note to St Peter, I think Al will have some optimization enhancements for you.

Al was a great guy! He always had a twinkle in his eye and a smile for everyone he met. Conversations with him were always interesting. We were lucky to have him in the Cal Poly Math Department for his second career.

Our deepest condolences to Judy and to Al's children and grandchildren. All of us in S. Florida have wonderful memories of the trips to the beach and the great family gatherings that he loved so dearly. Al was -much like his dad- a great practical joker. He was always quick witted and was the first to have fun with any given situation at any given time. His passing was so unexpected by all of us but the memories that are left behind will always be remembered as will he. RIP primo...

I had the honor and pleasure of meeting Al at my summer job (later becoming my first real job). Al was down to earth, had a great sense of humor, and warm - he was certainly as great a human being as he was an incredibly smart man. My sincerest condolences to the family.

Everyone at CADI in the early 80's loved Al. On my very day on the job out of college, nobody else was around to go to a customer site to solve a problem for them. I had no ideas how to do it, but he gave me the basics and said, "Don't worry you'll figure it out, Shawn -- I know you can do it". And so I did.

Later I used to hang out in his office and discuss mathematical problems and paradoxes with him and Ramon Carlos. Great memories.

I will miss you, Al, and I'm so glad I had you in my life!

My condolences to the Jimenez family... Al was a wonderful man, and I am honored to have known him while working in the Math Department at Cal Poly. He was very respectful to and appreciative of the Department administrative staff, he was always the first to offer a helping hand, and he was upbeat and always had a smile whether just returning from a long day of teaching or arriving after his bike ride to work. He was a true gentleman.
