hi ,

i've run up-to-dated macroplacement flow (add code flow), openroad is install and pass recursive check in my machine, and openroad (setup.tcl) is pointed to my local build path.

I found error in: gridding = GriddingLefDefInterface(gridding_src_dir, design, setup_file, tolerance, halo_width, openroad_exe) line 297 self.ExtractInputs() line 345

error is : FileNotFoundError: [Errno 2] No such file or directory: '/home/*/Desktop/MacroPlacement-main/CodeElements/CodeFlowIntegration/rtl_mp/ariane.hgr.outline'

could you kindly help me check this issue?

[diaoerlie]

here's file generated in rtl_mp

positon.txt io_net.txt ariane.hgr.blockage top_glue_logic_macro_cluster_0_part_0.txt.block ariane.hgr.net ariane.hgr.block top_glue_logic_macro_cluster_0_part_0.txt.net

[diaoerlie]

by the way , i've also used Desktop/MacroPlacement-main/CodeElements/Gridding/test/test_gridding.py the error is the same

Hi diaoerlie, I think it's related to the openroad binary. Since we have got many feedbacks about OpenROAD. Could you do a git pull and build your own OpenROAD binary (https://github.com/ravi-varadarajan/OpenROAD.git), then retry ?

hi zhi ang,

I've build openroad locally from public git : https://github.com/The-OpenROAD-Project/OpenROAD do you mean, i should use this git? https://github.com/ravi-varadarajan/OpenROAD.git

[ZhiangWang033]

Yes, the codes are different.

[diaoerlie]

thanks i will try it

[diaoerlie]

it's seems work, let's wait and see

[diaoerlie]

hi zhi ang,

here's what we generated, after python3 flow.py:

ariane.hgr.vertex ariane.hgr.outline ariane.hgr ariane.hgr.part.637

my question is : how to combine (or feed) this output into P&R tools (openroad / innovus)

thank you so much

[ZhiangWang033]

No. You cannot do this. the code elements are used to replicate the gridding/grouping/clustering. I am not clear what you want. Do you want to run Circuit Training ? Or do you want to run Gridding/Grouping/Clustering ?

[diaoerlie]

i‘d like to use circuit training, and use CT's output feed into openroad / innovus tools and run place and route.

Hi @diaoerlie, Just for your reference: You can use the plc_pb_to_placement_tcl.py script to generate the macro_place.tcl file. This you can source in the innovus shell to generate the macro placement.

Here is an example of generating the macro_place.tcl from the final *.plc file and the protobuf netlist. python plc_pb_to_placement_tcl.py rl_opt_placement.plc netlist.pb.txt macro_place.tcl

@ZhiangWang033 a suggestion that you might need to change the description of "git clone --recursive https://github.com/The-OpenROAD-Project/OpenROAD.git" to "git clone --recursive https://github.com/ravi-varadarajan/OpenROAD.git"

:)
