Problem in simulating a circuit with spectre

pdatta

Hi

I am new with linux and cadence. So, the problem I am facing may be a very simple one. But I couldn't find any solution in google and hence, I'm posting. I installed Cadence custom IC 6.15 and MMSIM 12 using iscape in ubuntu 12.04 32 bit OS.Then I installed NCSU freepdk45. Everything seem to work fine. When I run virtuoso, no error or warning in the cds.log file.

But problem occurs when I try to simulate a circuit. I tried to simulate with spectre (I don't have license for hspice). In doing the simulation I did the following things:

1. Initialize the spectre (simulation run directory: spectre.runl).

2. Lunch ADE L, choose simulator/directory/host

3. define model card path, set the stimuli 

4. choose the analysis,  select outputs to be plotted on schematic

5. then choose netlist and run.

When all of these are done I get an error message in the cds.log stating:

ERROR (ADE-3036): Errors encountered during simulation. The simulator run log has not been generated.

        Possible cause could be an invalid command line option for the version of the simulator

        you are running. Choose Setup->Environment and verify that the command line options

        specified in the userCmdLineOption field are supported for the simulator.

        Alternatively, run the simulator standalone using the runSimulation file in the netlist

        directory to know the exact cause of the error. 

So, if you please help me solving this problem, I would really appreciate it.

  • It's not Virtuoso you're having the issue with, but MMSIM. The issue is that MMSIM11.1 and later require a 64-bit OS, and you're trying to run on a 32-bit OS. Given that no recent hardware has been 32-bit, you're either running on a very old machine, or have installed a 32-bit OS on it for some peculiar reason. There may be other issues too, but if running "spectre" from the command line (which is what runSimulation does) fails, then that's where you need to start.

    Note that Ubuntu is not supported at all by any Cadence product; that's not your issue here, but it quite likely will lead to problems.
