Dear all,
I experience problems when I set up a corner analysis using ADE and then export it to an OCEAN script
(or even without exporting it).
Basically, in the OCEAN script there's a statement like this:
Code:corSetMeasExpression( "ton" "(cross(VT(\"/up\") 0.9 -1 'falling) - cross(VT(\"/up\") 0.9 -1 'rising))" )
Of course, for corner analysis, I would like to replace the fixed 0.9 by Vdd/2.
Vdd is certainly a parameter of my netlist and added to my corner setup file .pcf.
When I replace the above code by the following:
Code:corSetMeasExpression( "ton" "(cross(VT(\"/up\") "Vdd/2" -1 'falling) - cross(VT(\"/up\") "Vdd/2" -1 'rising))" )
my OCEAN corner script is not able to output these results over corners. Furthermore, the corner analysis GUI
reacts in the same way (only a fixed number works...)
Has anyone a solution for this? I can't imagine this cannot be setup under Cadence...
Kind Regards
Peter
