Arithmatic - SPICE statement to SPECTRE or PSPICE

Arithmatic in PSPICE

Hi ,
I would like to covert the following SPICE statement to SPECTRE or PSPICE . How do I do
E_1_EB 711 15 VALUE = {(10*V(73,500))/(V(521,500)+0.005)}

Re: Arithmatic in PSPICE

Hi Pramod,

Any specific reasons for the conversion ? I am not sure how you can do but its simple to achieve in Pspice..

For Node "E_1_EB" evaluate the expression from PSpice >> Trace >> Add trace simulation window..Hope this helps

Hi,
I do not want to see this in evaluation window, in fact this statement is part of netlist as shown below, and it does not execute in Spectre or PSPICE
