[Gnucap-devel] Storing data in Gnucap

[Xavier Romeuf]

Hi,

I am working with Cyril Giraudon on a Python wrapper for Gnucap. I would 
like the wrapper to be able to obtain the results of an analysis to work 
them from the Python environment.

In Gnucap, the standard way seems the ">" option as follows:

gnucap> get aCircuit.ckt
gnucap> print tran v(4) v(5)
gnucap> transient .00005 .0001 0 > file

So the results can be obtained by parsing the output file.

However, while looking at the source code of Gnucap, I found in 
s__out.cc the SIM::store() method which is not yet implemented. Its 
comment is "will store data in preparation for post processing".

Does it mean that this method would be able to store the results of an 
analysis in memory (and so the results could be directly read by a 
wrapper without using a file)?

If so, how would this method be used? Called from another method 
(SIM::outdata()?) or after using a command like:
gnucap> store tran v(4) v(5)
gnucap> transient .00005 .0001 0
?

If SIM::store() does so, I can try to implement it...
A possible way would be to extend the probes contained by
PROBE_LISTS::store[_mode] by making them to store the analysis results. 
For instance, they could contain a std::vector member filled by 
SIM::store().
Would it be suitable?

Regards,

Xavier
