XDM 2.7 Xyce diode parameters not up to date

[tvrusso]

Xyce 7.7 contains a number of updates to the diode model that included a new instance parameter and a number of new model parameters. The file XDM/src/python/xdm/inout/xml/schema/xyce.xml does not have those updated parameters, and therefore if I understand it correctly they will be ignored when converting from netlist formats of simulators that do have those parameters.

Another thing: it does not look like the hspice.xml file section for the diode contains the sidewall parameters. spectre.xml does have a "perim" instance parameter which probably maps to Xyce's (and ngspice's, and hspice's) "PJ" parameter, and has the sidewall model parameters.

HSPICE itself does have those parameters, but XDM seems not to be set up to recognize them or convert them properly.
