  • Video Demo: Your Maiden Voyage Across OCEAN

    I still remember my first encounter with OCEAN. It was 2002 and my co-worker had asked me to run a simple test for him. I sat in my cube, ruffling through our user guides, trying to quickly learn just enough to do the task at hand. The story ended happily, but I sure would have saved some time and frustration...

  • Monte Carlo simulation puzzle

    Dear All, I know in Monte Carlo simulation, we can define the correlations between two devices. Now in the simulation, I have two instances of same module called "PGA", in the Monte Carlo simulation, I want to check the mismatch effect inside module "PGA", but I don't want to...

  • OCEAN Parametric analysis

    Dear all, I am running parametric analyses with an OCEAN script. It finishes and all the output variables are correctly evaluated. I calculate two variables L_opt and eff_opt, that are single values, not array and I try to write them in a file. Trying to write the data in the file OCEAN generates the...

  • Question about Parametric Sets

    Hi! What about parametric sets? e.g. paramAnalysis("X" ?values set_x ?sweepType 'paramset paramAnalysis("Y" ?values set_y ?sweepType 'paramset)) paramRun() How can i have access to data and the set of sweep values? Regards, Candido Duarte

  • Printing to file after running Parametric Analysis

    Hi, I am running an ocean script to do a parametric analyis. The parameters are VDD and temperature and analysis is transient. The script goes something like the following, paramAnalysis("VDD" ?values (3 5) paramAnalysis("temp" ?values(-40 125) ) ) paramRun() openResults(dir) selectResults...

  • Ocean Script For MonteCarlo Simulation shows incorrect results

    Hi All, My script for montecarlo simulation finished successfully, no error displayed. My script uses for loop so that I can run montecarlo simulation in 5 different corners. I use monteExpr to get simulation results. The results are stored in 5 different directories. However, the results have some problem...

  • Ocean script confusion: illegal duplicate field symbol in list of fields

    Hi all, I run ocean script for Monte Carlo simulation. In our model file, we just have mismatch parameters (the foundry do not have process variation for Monte Carlo simulation), so in order to run Monte Carlo simulation, we use for loop structure to run Monte Carlo simulation for each corners (TT, SS...

  • Ocean script sample for MonteCarlo simulation

    Dear all, I am new to Ocean script, I am wondering if somebody give me a sample of ocean script for monte carlo simulation. Links, or paste at here works. Thanks a lot

  • Ocean Script error--branch distance too far from generated code

    I met a very wired question these days related to a error: branch distance too far from generated code . Attached please find my ocean script. I will try to discribe the problem in detail, hope some super guys such as Andrew Beckett and skillUser see it and give me some hints. In the attached script...
