Forum Post: RE: Most efficient db function to move all shapes in a design?
I'm not sure how many times I have to say that -nograph is running the same way as in graphics mode as far as icfb is concerned. The memory allocation is the same. Derek was merely explaining that if...

Andrew thanks for the answer, but also, let's say I have schematic with two devices using the same model with that parameter. And during the simulation I want this parameter to be changed only for one...
View ArticleForum Post: RE: Referencing a model, not a model instance
Hi Andrew, Thanks - I am trying to go the new MMSIM route (and hope everything will work with the PDK). I asked our CAD administrator to install the latest MMSIM version. But it contains Spectre 15.1.0...
View ArticleForum Post: RE: Referencing a model, not a model instance
MMSIM subversion numbers show a build number (which increments in fairly big chunks), but if you run "spectre -W" it will also add the subversion on the end. Looking at the downloads.cadence.com site I...

This is a very odd thing to do (even if you wanted to change all of them) because of course you can't really change the model parameters during real life (unless maybe you are trying to emulate aging...

Rather than dynamically adding and deleting the fields, I updated the code to do what you had attempted to do - just make the field invisible or visible. The key things I altered: Make the invisible...

Hi Andrew, I am afraid I need to bug you once again on this - thanks for your perserverance ;-) I think I have indeed the correct MMSIM installed (the one you mentioned): $ spectre -W sub-version...

The versions are fine. If you use spectre -W it shows the subversion number, whereas spectre -V it shows the major version umber and build date. This is a hotfix of MMSIM15.1 which is why it came out...

Thanks for your answer! My first problem has been solved. Now I have a different problem. After the routing, I want to calculate delay of the specific path in the design. I know that I can do this from...

Hi everyone, I have a question regarding netlisting, matlab, spetre and the mosfet model. From what I understand, when we run a simulation using spectre, a netlist is created which will be fed to the...

Hi Andrew, I again played around for an hour. I managed to get rid of the warning but the option still need to be ignored. I think the spectre version is correct, the noiseoff_type option is known in...

Hi Andrew, Thanks for your answer. Using '(t)and '(nil), it's a stupid error from my side, since I am still learning SKILL. Regarding the "-1" values, it is just a note for me as, in the future, if I...

OK, a couple of things here. First, the reporting of noiseoff_type in the log file. This is not the friendliest reporting in the log file, but the way that all options in spectre which have names as...

p.s. I tried the latest QRC (16.1.1-s111) and the R extraction results were the same as 14.2.0 - some connections to sub-nodes of vdd/vss were repeated even though the devices were physically seperated.
