I see some old posts related to this. Not sure where we are today. Here's what I'm trying to do :
Generate a netlist in batch mode; generate the runSimulation file; copy the run directory; launch the sim in the copy directory with the runSimulation command. Problem is that that ocean script you get from ADE > Session > Save Ocean Script is totally inadequate.
I started off with createNetlist(?recreateAll t) but found that not all components of the design were showing in the netlist directory. Worst of all, no runSimulation file.
I searched support and found runams -netlist. But the note says it doesn't work for cellview based netlisting, only OSS.
Luckily, support also had something on asiGetSimulationRunCommand.
This led me to sevNetlistFile. Unfortunately, when I try this
Loading simui.cxt*Error* slotValue: no such slot - simID
A few points/questions:
In reply to Andrew Beckett:
Thanks for replying.
1. I won't get into this.
2. I thought it was missing things, but, somehow, when you hit run(), magic happens and all the stuff I would expect to be there at netlist-done time get created.
3. I've been using ./runSimulation for years. I feel powerful being able to script and automate. GUI's are good for the first run, but we must give users control.
4. True, this works :
/* Style Definitions */
mso-padding-alt:0in 5.4pt 0in 5.4pt;

Question, why would the manual tell you sevNetlistFile( sess 'recreate) (which doesn't work) and not say anything about this use model?
I understand a lot of effort has gone into building what we have. I'm not trying to disparage it. If I said it was perfect, that would be bad - coz there would be no room for improvement. From a user experience point of view, there is a LOT of room for improvement.
In reply to swdesigner:
re your question - sevNetlistFile(sess 'recreate) does work (I just tried it, in case there was a bug, but since it's used in ADE that seemed unlikely). You have to pass it the right kind of session - and obtaining that is documented in the same manual (with sevSession()). I don't understand what you mean by "not say anything about this use model". If you mean running with runSimulation, then that's not documented because it's not the expected (or supported) use model. We do tell you how to run simulations using OCEAN (e.g. the run() function). The sev.* functions are primarily there to interface with the ADE environment.
So I guess I don't understand (quite) your question?
BTW, the whole point of OCEAN was to give people additional control and to be able to do things in a scripted fashion - we recognize user interfaces don't always fit everyones needs. Similarly people create netlists and run the simulation outside Virtuoso (not necessarily using the runSimulation command because they can provide the arguments to spectre themselves, or whatever). Scripting and automation is a good thing, I agree!
