Hi all, I met a problem like below when running "make run-precheck" [ERROR] - MPW Precheck failed to get Open PDKs & Skywater PDK versions: Command '['git', '-C', '/home/ren/Projects/caravel_tutorial/pdks/open_pdks', 'rev-parse', '--verify', 'HEAD']' returned non-zero exit status 128 [ERROR] - XOR CHECK FILE NOT FOUND in /home/ren/Projects/caravel_tutorial/caravel_example/precheck_results/01_JUN_2022___09_03_09/logs/xor_check.total [CRITICAL] - {{FAILURE}} 2 Check(s) Failed: ['Default', 'XOR'] ! I am new to this Project. Is there anything maybe related to this ERROR? Thank you very much.

@jeffdi fyi

You can ignore the first error (pdk versions). But must fix the 2 critical errors - default and xor.

Thank you for the information! But is there any idea about how to fix that?

XOR checks Only User Power Ring (8 Power Ring) against Golden reference. Hope you have used default power ring configuration.

Thank you for the information. But I met a new "ERROR [ERROR GRT-0039] Found pin outside die area in instance basic". when executing "make user_project_wrapper" Does that because the the die area in config.tcl is not big enough?set ::env(DIE_AREA) "0 0 2000 2000"

In MPW user_project_wrapper default area size is set ::env(DIE_AREA) {0 0 2920 3520} this value should not be changed. User can have different die area for sub-harden blocks only.

@Ren Yinghao load your DEF file with

openroad -gui

and check how its placed. If needed increase your DIE_AREA.

in MPW user_project_wrapper default area size is set ::env(DIE_AREA) {0 0 2920 3520} this value should not be changed other-wise you will have pre-check XOR failure.

I set the area in user_project's config file the biggest 2920 3520. But it stills gets [WARNING GRT-0036] Pin wbs_dat_o[21] is outside die area.

Error: groute.tcl, 69 GRT-0039 things like this. does that because the area is not big enough for this project?

can you attach the test case?

https://github.com/Ricardo-Ren/NN_openMPW/tree/first Sorry for the delay. This is the Project. Test case means the test module?

@Ren Yinghao set ::env(DIE_AREA) "0 0 2900 3000" is the required DIE AREA? how you choosen?

I just want to set it as big as possible🥲

@Ren Yinghao

set ::env(FP_SIZING) absolute
set ::env(DIE_AREA) "0 0 2900 3000"
set ::env(PL_BASIC_PLACEMENT) 1

Remove above variable and use:

set ::env(FP_SIZING) relative

can you file github issue with

?

Thank you. I passed the first and the second make. But met the error when executing make run-precheckXOR CHECK FILE NOT FOUND in caravel_tutorial/caravel_example/precheck_results/03_JUN_2022___07_54_50/logs/xor_check.total {{XOR CHECK FAILED}} The GDS file has non-conforming geometries.🥲. Very sorry to ask you so many times.

I have this issue too - it fails locally with this problem but passes on efabless website

Thank you for the suggestion! So you mean my project may also pass on the website?

yes probably
