#162 NGSPICE model referencing based on .spiceinit Pull request opened by KrzysztofHerman Major change in the operation of the ngspice and PDK models. A .spiceinit was added under libs.tech/ngspice/. Since the pdk directory is referenced there it allows to stream the netlist without user specific location of the .lib files ie. .lib cornerMOSlv.lib mos_tt The second change refers to the central location of the psp103_nqs.osdi model which is now situated in libs.tech/ngspice/openvaf. There is no need to use pre_osdi psp103_nqs.osdi in the spice netlist anymore. The above changes affected xschem and qucs-s examples, which were also updated. In the case of qucs-s also the examples are copied to the user's .qucs directory and appear in the GUI in the project left pane. Some solutions were adopted from PR #120.

Hi @Harald Pretl, could you please review this PR ? Now the major change is that ngspice uses

$PDK_ROOT

to reference the libraries. Also OSDI file is placed in a fixed location libs.tech/ngspice/openvaf.

@Krzysztof Herman I love this change! Finally, I need to confirm proper operation in our image, but using $PDK_ROOT is the way it should be 🙂 The only thing not really clean with this: You assume the psp103_nqs.osdi is in the correct PDK folder, but you don’t ship it (I understand the license issue). So users have to run the setup script, and I need to put the osdi into the right place when building the container, but that is fine. At least I don’t have to patch all your Xschem examples any longer, because I removed the osdi statements from them (not needed in our image).
