Oceanscript

  • 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...

  • 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...

  • Re: ocean script - input.scs copy

    I'm not explicitly answering your question, but if you were willing to run your simulation entirely within Ocean, you can send the simulation results wherever you like with: design("LibName" "CellName" "viewname" "r") netlist_dir =strcat(envGetVal("asimenv...

  • Re: OCEAN simulation used for envlp analysis

    Thanks for your answer! The version of icfb is 5.1.0, the sub-version 5.10.41.500.5.96! If I generate the netlist in an OCEAN script, in the file input.scs there is not the clockname, as shown in the following lines: " envlp envlp harms=1 stop=200u errpreset=conservative readic="enc.fc"...

  • OCEAN simulation used for envlp analysis

    Hi, I have a problem executing envlp analysis through OCEAN scripts. If I try to execute the simulation with the graphic interface, all is ok, but saving the script and executing it, an error stops the envlp simulation. The error is: " Error found by spectre during envelope following analysis `envlp'...

  • ocean problem &ocnPrint!

    I write ocean script for parameter analysis and use ocnPrint to print some simulation result. For example: fp=outfile( "./paramResults.out" "a" ) risetime_netA=riseTime(clip(VT("/C5") 5e-08 9e-08) 0 nil VAR("core_voltage") nil 10 90)*1e09 ocnPrint(?output fp ?numSpaces...
