Title: Help: Cadence error: V5: Waveform type must be specified if any waveform paramet
Post by lunren on Feb 24^th, 2009, 10:55am

I use Cadence to work on a project, but there is a error: V5: Waveform type must be specified if any waveform parameters are given.
I search internet, it seems that lot of people meeting this problem, but no good solutions. Anybody here can give some ideas?

Another problem is that dependent sources from analogLib can not be used. For example, when I set the gain of vcvs to 2 and extract netlist, the gain parameter can not be extracted. The netlist is always like this:
E1 (net1 net2 net3 net4) vcvs
The gain=2 parameter is always ignored. How to deal this problem?

I don't know about the second problem, but on the first the message says it all: you have to set the waveform type. Look for the waveform type parameter and set it.

This has the ring of failing to do:

Code:

setenv CDS_Netlisting_Mode Analog

before starting DFII. If you don't have CDS_Netlisting_Mode set to Analog, any parameters which are at their CDF default values do not get netlisted (this is because the spectre netlister can be used with both "NLP" (i.e. Digital) or "CDF" (i.e. Analog) based netlisting.

Try setting this UNIX environment variable, and see if that solves it.
