This is caused in your code by lines 94, 127, and 130.

No standard cells can be synthesized with the default method for

make user_project_wrapper

. Line 94 is a problem because

2'b00

requires two "tie low"

conb

cells.

Lines 127 and 130 are a problem because they both require an inverter cell (i.e. for

~

)

You can change line 94 to simply:

assign user_irq[0] = user_sys_irq;

-- you don't need to assign the other 2 bits at all (so long as you keep the respective IRQs disabled in firmware, which is their default state anyway)

Lines 127 and 130 will require that you change your macro's logic internally (i.e. inside

i3c_dut_top

) to generate those signals with the correct (inverted) polarity.

There is an alternative, and that's known as "top-level hardening" (or top-level synthesis) but it comes with other challenges, so I suggest you don't go down that path for now.

One other thing to check: your design's macro is called

i3c_dut_top

-- have you already run

make i3c_dut_top

(and hence do you have it hardened as

gds/i3c_dut_top.gds

? If not, you will need to run that

make i3c_dut_top

also to generate your macro.

To be sure we're not missing anything else, I suggest you also share your

openlane/user_project_wrapper/config.json

file and

macro.cfg

from the same directory.

Thank you for your support. The error is now cleared. But in STEP 5 : Performing manual macro placement. it get error. Kindly help to resolve this issue.
