Macro not found in Macro placement #852

Closed microSharjeel closed 2 years ago

microSharjeel commented 2 years ago

Hi, I am trying to place a already hardened Macro in my design. I have followed the manual_macro_placement_test design example and am encountering the following error Traceback (most recent call last): File "/openLANE_flow/scripts/manual_macro_place.py", line 119, in assert not macros, ("Macros not found:", macros) AssertionError: ('Macros not found:', {'ram': ['5590', '168230', 'N']}) If anyone can guide me what is the problem why OpenLane can not find the Macro although the .lef and .gds files are there in Macros folder Kindly guide regards

@microSharjeel are you trying built-in example or your own design? If its your own design mean need re-producible tar file needed with environment survey

microSharjeel commented 2 years ago

Thanks for reply I am attaching the tar of the design since the design is my own. I am just trying to place macros of an SRAM in my design the .gds and .lef files are there in the Macros regard iob_sp_ram_be.zip s

Are you able to reproduce the error best regards

vijayank88 commented 2 years ago

@microSharjeel Refer built-in example manual_macro_placement design from openlane, it will work. From your config.tcl dont use both DIE_AREA and FP_CORE_UTIL... Next src/.v add (blackbox*) before module definition. Format available in built-in example

Test cases should be packaged with https://github.com/The-OpenROAD-Project/OpenLane/blob/master/docs/source/using_or_issue.md

microSharjeel commented 2 years ago

This issue is resolved by following the built in example of OpenLane

hello If possible, I would like to know how you finally solved this problem? I encountered the same error as you, also using openRAM using sky water130. Thanks a million!!

microSharjeel commented 2 years ago

@0616ygh can we connect on google hangout etc I hope it will be mutually beneficial connect at sharjeelsaeedkhilji@gmail.com

0616ygh commented 2 years ago

@microSharjeel I'm sorry but I don't have a google hangout...I'm a student from China mainland, we don't have hangout QAQ My question is that after I read Openlane->design->manual_macro_placement_test, I find I don't have :

set ::env(MACRO_PLACEMENT_CFG) $::env(DESIGN_DIR)/macro_placement.cfg set ::env(BASE_SDC_FILE) $::env(DESIGN_DIR)/base.sdc

these 2 files can't be found in OpenRAM package... 1
