unplaced macros during PDN stage

[vijayank88]

@oharboe
I came across your test case https://github.com/The-OpenROAD-Project/OpenROAD/blob/master/src/pdn/test/macros_cells_not_fixed.ok
I am also facing similar error with macro_placement command followed by PDN stage throws error.

[WARNING PDN-0234] spm_inst_0 has not been placed and fixed.
[WARNING PDN-0234] spm_inst_1 has not been placed and fixed.
[ERROR PDN-0235] Design has unplaced macros.
PDN-0235

How to resolve this error?
Thanks in advance...

@maliberty @vijayank88 I dont recall making this test case...

[vijayank88]

Ohh sorry about that. I just seen last commit. Actually it's added by @gadfort .

[gadfort]

@vijayank88 it means you have macros in your design that have not been placed. PDN will only consider placed and locked macros and therefore requires all macros to be locked. Look at your design to find the two macros that have not been placed and locked and fix that

[gadfort]

@oharboe yes you are correct, macro placement or row cutting/tap cell insertion should probably also have generated some error.

here is macro placement test case. Same thing updated in OpenLane issue as well.

@gadfort
can we continue the discussion in OpenLane issue itself?

@vijayank88 I'm not a user of the openlane flow, so I'm not sure I can be of much help since its not an issue in any of the tools I support. You should check with the maintainers of OpenLane

[vijayank88]

Ok.. understood. I will wait for OpenLane team response
