Pulpissimo synthesis

[MikkeN]

Hi,

are you having some scripts or tools to help making correct code parsing for synthesis?
I have made my own list, but don't know which files should be included. For example there is axi_slice_dc_master_wrap.sv under axi and pulp_soc.
Is there some automation hidden for src_files.yml files under IPs and RTL?

Currently when running synthesis with dc_shell, it gives errors from some of IPs. I assume that those are not needed in Pulpino implementation.

Hi, I cannot try right now but you should be able to generate that by adding something like this to the generate_scripts script in the PULPissimo root (assuming you have a directory called 'synthesis/analyze'):

ipdb.export_synopsys(script_path="synthesis/analyze", source='ips')
ipdb.export_synopsys(script_path="synthesis/analyze", source='rtl')
ipdb.generate_synopsys_list("synthesis/analyze/ips_add_files.tcl", source='ips', analyze_path='scripts/analyze_auto/ips')
ipdb.generate_synopsys_list("synthesis/analyze/rtl_add_files.tcl", source='rtl', analyze_path='scripts/analyze_auto/rtl')

hello，
Have you done pulpino synthesis？I am doing synthesis for pulpino，and encountered some difficulties，if you have done synthesis for pulpino，can I get some help from you？

What about PULPino？I am trying to synthesize PULPino，Can PULPino do this too?

[MikkeN]

Zhouqinang, I have synthesized Pulpino over year ago. Here are files you need to analyze with commands to Synopsys Design Compiler (I can not quarantee that this is situation today)

Hello MikkeN,
Thank you so much for your generous help! Have you tried generating SRAM and boot_rom? Then after the DC is completed, have you simulated it with the generated netlist? How should the simulation after this be done?

Hi,

are you having some scripts or tools to help making correct code parsing for synthesis?
I have made my own list, but don't know which files should be included. For example there is axi_slice_dc_master_wrap.sv under axi and pulp_soc.

Hello Mikken，
     Sorry to bother you again. Now I am trying to write sdc file for synthesizing the PULPino, but the clock for PULPino seems to be a liitle complex, from the vivado .xdc file, it seems that there are three asynchronous clocks, so my question is how should I write sdc file for the PULPino? If you have wrote sdc file, can you share it with me?
