Forum Post: RE: Extracted simulation not working properly - netlist problem...?
Francesco, It's more a case of being able to debug a problem without a blindfold on, which is easier to do via the normal support channels. There's typically quite a lot I can do in the forums, but it...

Given that in VerilogA it's quite straightforward to write equations for a conservative system, it must just be that you've not captured the equation correctly. You can write an equation that relates...

Sherif, You didn't mention which IC version you're using, but my guess is that it's IC617. DEFT has been removed from the form in IC617 as the first step along the way to it being removed altogether....

Hi Menghan, I'm not sure what this "discrepancy" is relative to; I would expect results to be more accurate with conservative and a relative tolerance of 1e-4, but I don't know what you're measuring or...
