Default (or script) ADE Stimuli

meland

Hello All,

I am wondering if there is a way to either alter the default ADE stimuli or change it through script. I would prefer if all of my stimuli would default to a 0v DC source which is enabled. 

I suspect that this is done in some way through the asi function calls in the ADE L Skill reference manual, but I'm not able to figure it out. I have some level of skill experience, but I have never skill scripted anything with the ADE.

I work in both cadence 5.1.41 and 6.1.5, but if there is not an easy method for cadence 5 that is fine.

Perhaps my overall approach is flawed though and there is a better way of doing what I want. My overall goal is to more easily set up and test at higher levels where there are potentially hundreds of stimuli. I haven't found a way which works well for doing this. Going through and editing one by one is quite tedious. I tried vector files, but I couldn't do anything bigger than a 4 bit bus . I had issues scripting a general stimuli file (An issue I had scripting the two of these was getting cadence to return the pins with the buses expanded and keeping reference to the pin direction). I could also do AMS, but I do not know an easy way to set up AMS and have never gone down that road. Note, I do not have an ncverilog license available

Some direction on how to go about this would be great.

Thanks,

-Matt

     Hi Andrew,

     Sorry my first question was misleading. I'll try to be more clear in the future. I consider myself warned as far as using private functions.

     I have a follow up question. The code which I've provided works great for me when there are just a few input signals. However, it appears that this solution has some kind of memory leak issue. I tried running this on a block with 100 pins and the first few run fine, but each progressive setting of a stimuli takes slightly longer and longer. I noticed when it was approximately half way through the list it was taking ~6 seconds per stimuli. And it would just get longer to the point where the best thing to do is walk away for a little. 

     Is there some way around this that might not take as long? It seems the issue is with the line 'formId->artStmBox->value = list(choice)' but I'm not sure any other way of doing this. 

     Any idea what is going on here?

     Thanks,

    -Matt
