Ocean Script

  • How to close a netlist in Ocean

    I’m running an ocean script that runs multiple PVT corners in a nested foreach loop (see sample below). It runs all the PVT corners in parallel using LSF. The problem I’m having is that at each corner, the run generates a netlist. With post-layout extraction, the netlist could be ~100M, and...

  • Run ADE XL with ocean scripts

    Hello, I'm trying to run a Custom Analysis running MPP2 with an ocean script but I have the error : ERROR (ADEXL-1529): No samples specified for the test 'work_Mohamed:ampdiff1:1'. Specify the samples for this test and then run the simulation. ERROR (ADEXL-1600): Cannot find an active session...

  • Re: Getting schematic instances from multiple open schematics

    Thanks. Both are excellent suggestions. But I'm doing this to select instances for an ADE-XL session. So I found an easier way to do this & tired using "asiSelectInst" with this code: ;get a unique form handle win = sprintf( nil "%s" hiGetCurrentWindow() ) form = concat( 'iphdcopTabForm...

  • Error in storing output data into file

    Hi experts, I am new to cadence ocean scripting. I need to store the data of output wave that is generated, into a file. I am able to print the output value at a certain instant say the max value of the output wave using the following code. V=ymax(v("/V" ?result "tran-tran")) fprintf...

  • How to parallel or to increase the speed of simulation launching with ocean (distributed)

    Hi, I wrote an ocean script which has to do lot of simultations. It is working perfectly well but I would like to increase its speed. Currently I use run( ?jobName jobname ?queue lsf_queue ?mail nil ) to launch the simulations, and the following environnement variables: envSetVal("asimenv.distributed"...

  • Execution of ocean script in Cadence IC 6.1.5 and Cadence IC 5.1.41

    Hello, I started to work recently on the new Cadence IC 6.1.5 moving from IC 5.1.4. I use Ocean Scripts and noticed that the ocean script takes a longer time to execute in the new version than in the old one. To verify this, I took a simple inverter circuit and performed the DC simulation analysis using...

  • How to collect data after MonteCarlo simulation

    Dear all, I have performed the following MonteCarlo simulation through the ocean script to capture the current consumption for a time frame from 15ms to 25ms, how is it possible for me to re-collect the data, say from 50ms to 100ms, without re-run the simulation again? I am looking for a ocean script...

  • Ocean scripting - Plotting multiple expressions in different strips

    Hi, I need some help on this. I'm simulating an amplifier for many corners and need to plot gain and phase response. For the plots, I need appended plots (of all corners) of gain in one strip and phase (of all corners) in another strip. I tried doing the following in my script: Gain_plot=dB20(getData...

  • Memory issues with ocean script (Monte-Carlo+Parametric analysis)

    Hi all, (sorry for this loooong first post :) ) - I need to do a Monte-Carlo simulation (Virtuoso 6.1.5) for a RF circuit with N runs for different combinaisons of parameters (voltages V1 to V4) - For each of the 256 combinaisons I want to run a Monte-Carlo to evaluate 4 different parameters (like gain...

  • Re: How to convert string to symbol?

    Hi Andrew, How do you convert a string to a symbol or w_windowId? I am using Ocean and want to make the w_windowId variable in the hardCopy command from strings I created. This way I can change the windowId with my program based on other variables. I do not see the stringToSymbol function as described...
