create DSPF/SPICE cellView using SKILL

Albert 2 months ago

Hello,
Using Library Manager, I'm able to create DSPF and SPICE cellviews with the dedicated Cadence text editor. There's also a special button available: "Build a database of instances, nets, and pins found in file", which generates the necessary data and stores it under the view. After that, the view can be used in the config view without any additional actions to specify the DSPF/SPICE netlist location for the simulator.

However, I haven't found any SKILL functions that perform the same operation via the SKILL API.
Could you please suggest how to achieve this using SKILL?

Thanks in advance!

It is documented on the description of dbOpenCellViewByType, esp. fourth and fifth argument (viewType and mode), though maybe not that clear on first sight. So you may follow this article first and look at the documentation afterwards, than it gets much clearer:

Henker, thanks for the replay. Yes - I'm aware about dbOpenCellViewByType and "netlist" type as a fourth parameter - but this just creates dummy netlist.oa file without any information. And I don't see any possibilities how to add information about I/O pins.

Ah, sorry, I misread and assumed that view creation was the problem.

The public API behind the 'Build a database ...' button is hdlGenerateTextDatabase (available since IC6.1.7 ISR15). This creates the shadow database for analog and digital languages without requiring the text editor. It also creates the termOrder entry in the CDF simInfo and the property nlAction=stop, which are needed to have the netlist file of the view included in simulation.

You can actually locate this by checking your CDS.log:
After pressing the 'Build a database ...' button, you get an entry with "_teSaveAndExtract()" from the private text editor API (the naming is rather obvious). With that as starting point in the support, you'd get hits for hdlGenerateTextDatabase.

Thanks henker . I'd missed the fact that a public API had been added (previously there was a private function to do this. My mistake...
