ADE vs OSS netlisting

Hi,

I am able to use ADE to produce a netlist for a given schematic. ADE
is using these switch and stop lists:

simViewList = '("hspiceD" "spice" "cmos_sch" "cmos.sch" "schematic")
simStopList = '("hspiceD" "spice")

But if I try to obtain the netlist with OSS, I get these warnings:

Netlister: Can't find 'hnlHspiceParamList' property for element
'nmos33'.
etc.

This seems to make sense, since view "hspiceD" from element "nmos33"
does not have a hnlHspiceParamList.
However, view hspice from element "nmos33" does have
hnlHspiceParamList defined.

Why doesn't this happen with ADE also? Why doesn't ADE complain that
it can't find the hnlHspiceParamList for element nmos33? Does it
switch automatically to view "hspice", even if it isn't in the
simViewList?

Thanks.

Joao,

I am no expert, but I believe that the ADE knows what hspiceD is
inherently, but the OSS only knows hspice. When I try to populate my
simList (IC 6.1) with "hspiceD" instead of "hspice", I get an error
from the simulator interface:

si: unknown simulator "hspiceD"

Try changing the simViewList and simStopList to reference hspice,
instead of hspiceD, and see if that makes this problem go away, or
just throws a different error. BTW, hspiceD doesn't use the
hnlHspiceParamList, because it takes all the netlisting data from CDF
instead. That is why you don't get an error in the ADE.

Hope this helps,
Paul

 

Hi Paul,

Thanks. Your explanation is very useful, since it helps understanding
why this happens and how ADE and OSS work side-by-side.
