Running SigXplorer in Batch Mode

Hi Marcelo,

I've spent a lot of time working with the SPICE files underneath the GUI.  It is powerful, once you get the hang of it.  Some ideas for you:

1) Type "tlsim" at a command prompt for a dump of the usage options
2) There is a switch to run SigXp on a .top without running up the GUI, I think it is -nograph.
3) All the .spc files are produced, and then called from main.spc.  You only have to tell tlsim where to find main.spc.
4) There was a nice appnote on allegrosi.com written by Patrick Riffault on how to batch SigXp .top files, but I can't seem to find it at the new site.  Anyone know where it went?

Hope that helps,
Donald

Hi Donald,

Thanks for your reply.
I successfully "played" a bit yesterday with tlsim.
What I'm missing is something like you mentioned in item #4, a flow to get all the required inputs for tlsim from my design (from .top file to .spc files and any other required input).
I believe it should be part of what happens when selecting "Analyze>Simulate" in SigXplorer (Skill function run?), but I need to find some documentation about it...

Regards,
Marcelo.

Thanks !

I ran a .top simulation case that generated the *.spc in
sigxp.run\case0\sim1
For example, I obtained an interconnect.spc as follow:

.subckt DESIGN_icn_ckt 1 2
* Display all elements first
NTLidlPart_21 (1 0) (2 0)
+L=0.0254 rlgc_name=STL_1S_1R_5 file=./ntl_rlgc.inc

.ends DESIGN_icn_ckt


Later, I went to the command prompte, and input:
spc2spc interconn.spc
I obtained the following spice file, main_gen.spc:

.subckt DESIGN_icn_ckt 1 2

XTLidlPart_21 1 2 0 rlgc_sub1

.subckt rlgc_sub1 1 2 9999
X1_1a 1 100 9999 rlgc_sub1a
X2_1a 100 101 9999 rlgc_sub1a
X3_1a 101 2 9999 rlgc_sub1a

.ends rlgc_sub1

.subckt rlgc_sub1a 11 12 999
C1_1a 12 999 5.3456e-013
L1_1a 11 13 4.40665e-009
R1_1a 13 12 0.0611742

.ends rlgc_sub1a

.ends DESIGN_icn_ckt

.end

Hope this is helpful.
