[SI-LIST] Re: Software AppCAD

Hi Peter,

AppCAD is very much a free stand-alone tool that was not designed to interface 
with  commercial layout software.

It is very useful for quick calculations, e.g. you can choose a dielectric for 
your PCB and put in (or vary) the geometric dimensions of your microstrip or 
stripline, and AppCAD will calculate the impedance and a couple of other useful 
parameters.

Most features of AppCAD are heavily targeted towards RF design engineers, i.e. 
analog microwave designs. 

I made this last statement because I do not work for Agilent's RF division, 
therefore please do not consider this as the statement of an official 
spokesperson for that division. For the purposes of this reply I am just a 
satisfied AppCAD user.....

Best Regards,

        Herbert.

Hi, Nico

Thanks for your help. I want to extract trace parastic parameter from
Cadence's Allegro layout file. Then use these parameters to simulate SI with
HSPICE. As you mentioned, I have downloaded and installed AppCAD. But I
haven't found any interface for Allegro. So I don't think AppCAD can extract
trace from layout files. However, AppCad can caculate transmission line
characteristics impedance and reflection. Is that rignt ? Thanks.

Best regards,

Peter
