Title: Verilog-A defined units in Spectre
Post by adelaid on Sep 3^rd, 2014, 3:45am

Hello, I am trying to do the model of an optical phase shifter in Verilog A. For that I defined the following disciplines:

// Optical Discipline
nature Losses
access = Loss;
abstol = 1e-6;
units = "dB";
endnature

discipline optical_losses
potential Losses;
enddiscipline

nature Phase
access = Phas;
abstol = 1e-6;
units = "rads";
endnature

discipline optical_phase
potential Phase;
enddiscipline

the problem is that in spectre when I simulate then the module, the units are not corresponding with what I defined here. Instead of Loss(dB), and Phas(rad) it appears Loss(Loss) and Phas(Phas). What can be the problem??

Thank you in advance.

Adelaid,
the viewer shows the wrong units? Then it is a tool issue...
