I'm sure I have managed to do this in the past where I used the "Variables and Parameters" pane in ADEXL to alter a value of a component in an extracted view like a resistor say and sweep this value without going round the layout loop. If a montecarlo is being performed and you have saved a statistical corner which gave a bad result then you may want to sweep a component parameter in the extracted view without altering the netlist and rendering the statistical corner invalid. The "Variables and Parameters" pane is not available in the extracted view so I don't know what trick I used to do this. Anyone tried this?
This certainly works in IC616, because there's been explicit work on supporting it. I think at some point in the past it was also there for extracted, but maybe it was removed because it didn't work properly...
Can you try in IC616?
In reply to Andrew Beckett:
Thank you Andrew
I've just moved from IC615 ISR16 to a ropey IC616. Did you mean that the Variable and Parameters pane was available in the extracted view? Or were you refering to the Variation Aware Design flow to stich LDE effects back onto schematic? I cannot use the VAD flow as it is not supported at 40nm by TSMC only 28nm and below. I think I use to get around this by running an L simulation and editing the input.scs then running runSimulation from the comman line.
In reply to pirateKing08:
Er, Lance, I'm a bit embarrassed now. I just realised that the Variables and Parameters support in extracted views is coming in IC616 ISR3 (I was doing some testing before going on holiday in August). So it's not there yet. This is due at the beginning of November.
Not sure what's "ropey" about it, but maybe we can take that offline...
So no, I'm not talking about the LDE flow.
