Synthesing designs with ASAP7

[gudeh]

Hi everyone. I am using ORFS to generate data for my machine learning project. I am using Nangate45 and Asap7 to do so. I am able to synthesize the standard desings as provided in flow/Makefile. Now I am trying to extend my dataset by synthesizing the designs not available by default. I was able to synthesize swerv, and dynamic node with ASAP7. All I did was to copy and paste the folder like the following: "cp -r designs/nangate45/swerv/ designs/asap7/" and rename nangate45 to asap7 in the config.mk file (and remove any .json files, since they should provide gold parameters only for specific platform). This did not work with ariane, black_parrot, bp_be, bp_fe, and bp_multi. I am getting the following error right in the beginning of the flow:

Black parrot asks for fakeram45_512x64.lib, while ariane asks for fakeram45_256x16.lib, the files do not exist in the path. Other fakerams do exist though:

I don't really understand how fakeram works, and I was not able to find a similar error on the internet. Any ideas on what I could do?

Those designs require rams and they are not the same across PDKs. It takes some expertise to setup a new design and I suggest you just skip them if you are unfamiliar with the process.

Alright! Other than that, the tinyRocket design was actually able to run, although it is failing during floorplan. I am getting the following error, would this one also be too hard to fix? I am trying to increase die and core area, although I get the same error.
2_6_floorplan_pdn.tmp.log

Also, I would guess that going the other way around would be easier. For example, synthesizing ethmac with nangate technology, I should not get too many issues right?
