Hello together. I am facing a bug in magic. When instantiating my design via

make user_project_wrapper

in

[STEP 26] [INFO]: Running Magic Spice Export from GDS

it gets stuck and runs forever. The

26-gds.spice.log

log says:

Notice the incomplete last line, which does not change (at least) for hours. Any idea would be appreciated. Is it because I did not connect all ILA signals? I only connected the first 6 ILA signals. Info: We are using EF_SRAM directly instantiated without the wishbone wrapper. I will leave it running for the next few hours. Maybe it will recover.

@Christoph Thanks for reporting this. Couple questions: 1. What version of magic are you using?

magic -dnull -noc --version

2. When you open the gds file (in magic or klayout), does anything seem strange? Are the SRAM blocks properly abstracted? 3. Is this a mixed signal design? Do you have analog blocks besides the SRAM macros?

@Mitch Bailey Thanks for your fast reply. 1.

OpenLane Container (30ee138):/openlane$ magic -dnull -noc --version

8.3.413 2. still analyzing, I just noticed a missing clock signal 3. digital only

@Christoph The current magic version used in precheck is 8.3.471. I wonder if updating would make a difference.
