gain expression for PAC analysis in ADE
Jun 22nd, 2009, 8:04am
 
Hello All,

Does anyone know how to put output gain expression in  cadence ADE  for PAC analysis.?
At present I am will plotting it once the PAC analysis is over by selecting the PAC results,but I want to put expression before analysis similar to AC analysis

Regards,

Hi pancho_hideboo,
In AC analyis if you write gain expression in ADE e.g 20*db20("VT(/<netname>"),this expression will be plotted at the end of AC analysis.
But in PAC,once run is over I need to go and select the PAC results and then plot the gain expression using calculator.

Regards
Ramesh

Not correct. This has to be VF(). And "20*" is redundant.

No, you don't seem to be familiar with Cadence ADE.

Choose "ADE>Results>Direct Plot" for both ac and pac with "Add Outputs=On".
Or use result browser for both ac and pac. Then invoke calculator and do "get expression".

In anyway, you can get following expressions in output field.

db20( v("/<netname>" ?result "ac-ac") )
db20( v("/<netname>" ?result "pac-pac") )
