Re: gEDA-user: passing parameters to a subckt

[clif@xxxxxxxxxxxxx]

Howdy,

I've been playing with gschem, gnetlist, ngspice, and gnucap, and I would 
like to find a way to pass extra parameters to a .subckt.

eg. I would like to have a symbol with some attribs like this:

refdes		X3
model-name	POT
model		VALUE=10k SET=0.5
file		../spice_models/pot.mod

and have gnetlist spit out a line like this:

XU3 10 9 0 POT VALUE=10k SET=0.5

and pot.mod could be something like:

.SUBCKT POT 1 T 2 PARAMS: VALUE=1K SET=0.5
RT 1 T {0.999 * VALUE * (1-SET) + 0.0005 * VALUE}
RB T 2 {0.999 * VALUE * SET + 0.0005 * VALUE}
.ENDS

I've googled hither and yon, looked at gnet-spice-sdb.scm but couldn't 
find anything definitive. Is there some other attribute that you might put 
a list of parameters in?

	Thanks,
	Clif
