CCVS in subckt probing one level up?

drdanmc

Is there a particular syntax which can be used for the probe= part of a ccvs instantiation in spectre that would let me refer to something one hierarchy level up?

What I am looking to be able to do is create a cell that has a CDF parameter named probe.  I want to instantiate this cell (call it "mycell") into a higher level cell (call it "mytop").  Then I want to have one or more ccvs inside of mycell that can use voltage sources or iprobes in mytop as the probe instance.

The spectre netlist would then look something like:

subckt mycell(out, gnd)

parameters probe

H1 (out, gnd) ccvs type=ccvs probe=../probe

subckt mytop()

myv1 (sig1, gnd) vsource type=pulse .....

myp1 (pr1, gnd) mycell probe=myv1

ends mytop

Thanks

    Dan,

    I don't think this is possible - it would probably need an enhancement CCR to do this. No alternative comes to mind (although to be fair I only spent about a minute thinking about it).

    Regards,

    Andrew.

    Thanks. I'll just put a pair of pin on 'mycell' and include the iprobe inside of 'mycell'.
