For unspecified gate delays (logic and tristate gates), which PSpice would consider as zero, set the rise and fall delays to 1.e-12s (the minimum for Xspice). For dff, jkff, dlatch, and srlatch use the Xspice default 1.0ns for rise and fall delays. If the ngspice variable (ps_port_directions & 2) is true, write the translated subckt to stdout, with TRANS_OUT prefix, for debugging purposes. The user could edit and replace the translated subckt if desired.

prototype for Verilog-A integration using OSDI and OpenVAF
...
This initial prototype is capable of performing DC, transient and AC
analysis. Not all features of OSDI are supported yet and there are still
some open questions regarding ngspice integration. However many usecase
already work very well and a large amount of CMC models are supported.
The biggest missing feature right now is noise analysis.

(testing) add res, cap and multiple devices test
feat: use osdi command to load files
Previously OSDI shared object files were loaded from fixed directories.
This was unreliable, inconvenient and caused conflicts with XSPICE.
This commit remove the old loading mechanism and instead introduces the
`osdi` command that can load (a list of) osdi object files (like the
codemodel command for XSPICE). A typical usecase will use this as a
precommand in the netlist:
.control
pre_osdi foo.osdi
.endc
If the specified file is a relative path it is first resolved relative
to the parent directory of the netlist. If the osdi command is invoked
from the interactive prompt the file is resolved relative to the current
working directory instead.
This commit also moves osdi from the devices folder to the root src
folder like xspice. This better reflects the role of the code as users
may otherthwise (mistakenly) assume that osdi is just another
handwritten model.
