ocean ocnPrint append textfile

  • 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...

  • Re: ocean script - data print to file

    You r right. My appology for trying printing wrong net. It works now. Btw, if I wrote two or more ocnPrint command, output file "results.txt" always has 2 redundant lines additionally between in two ocnPrint. How can I avoid this? ------results.txt------------------------- nominal_freq 1G <unnecessary...

  • Re: OCEAN simulation used for envlp analysis

    Thanks for your answer! The version of icfb is 5.1.0, the sub-version! 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...

  • Re: ocean script: ocnPrint

    Hi Sirrius, I have not played with this just now, but I am somewhat surprised that using the p_port input to the ocnPrint function does not work. The way that I would expect to use this is to open the file in append mode, print to it with multiple ocnPrint statements and even fprintf statements, and...

  • ocean script: ocnPrint

    Hello All I am trying to write the entire wave (ie, time vs values) into a text file. The problem is that I am overwriting the file with the latest values of waves. What I need to do is to append the information in one file, as I execute my ocean script. Here is my piece of code: (some code here) ;run...
