Update: We have rectified the SPDX Compliance Check errors, but still the script stops after Check 7. Please consider this error to be urgently clarified at the earliest.

@Marwan Abbas Looks like it may be failing at the magic DRC step. @Daniel Giftson This is a local precheck, correct? Not on the platform, right? It looks like you’re using a pdk with commit 
7198cf6
. I don’t see this pdk in 
volare ls-remote
. Did you custom build it?
d
Yes. This is a local precheck. And I am following the exact steps as mentioned here - https://github.com/efabless/caravel_user_project/blob/main/docs/source/index.rst#section-quickstart
So what do we need to exactly change here - do we need to enable the version of Open PDK mentioned above for Sky130A?
By the way, we didn't custom-build it. And we installed pdk through "make setup"
m
@Daniel Giftson ok. Looks like you’re doing everything right. Does 
volare ls
return 
7198cf6
as the highlighted commit? What is the date?
What does this return when run in the project directory?
Copy code
grep OPEN_PDKS_COMMIT Makefile

This is what I am getting

what about 
volare ls
?

Thanks. I have to go out for most of the day, but hopefully this is enough information for @Marwan Abbas to look into it.
d
OK. It would be good if someone could solve this issue as early as possible, as we have got a precheck deadline for UNIC-CASS within next 10 hours.
Anyways. Thanks @Mitch Bailey

Ok. I was looking at the sky130 commit. Open_pdks commit matches. Sorry for the confusion. Can you share 
precheck_results/22_SEP_2023___22_50_19/logs/precheck.log
and any other files in the same directory with similar mod times?
d
Yes. Just a min

Thanks. It may take some debugging to get to the route cause. Are you able to share your updated repo so we can try to replicate the problem?
d
So you want me to share the updated repo link with you. Is it?
Can you confirm this?
@Mitch Bailey I have shared the updated repo with you through dm.

When I run the local precheck, I get 2 errors - OEB and LVS.
LVS is easy to fix. In 
lvs/user_project_wrapper/lvs_config.json
, change 
user_proj_example.v
to 
user_proj_mac.v
. OEB might be a true error. All your gpio’s have a default configuration of 
GPIO_MODE_MGMT_STD_BIDIRECTIONAL
. In this configuration, 
gpio[37:5]
are controlled by the mgmt_core by default. Fortunately in this mode, the user area 
io_in[37:5]
will be a copy of the input to the mgmt_core. On the other hand, the user area 
io_out[*]
, which are connected to non_fixed signals, will never be available on 
gpio[*]
. In order to output the user area 
io_out[*]
, the io must be (re-)configured in one of the 
GPIO_MODE_USER_STD
output modes and the corresponding 
io_oeb[*]
must be low. If 
io_oeb[*]
are low, user area output 
io_out[*]
will be driving 
io_in[*]
, so you might want to programmatically set each 
io_oeb
to high for input and low for output. In the current design, it appears that 
io_oeb
is unconnected.

Ok. Thanks for the assistance. Got the errors rectified and successfully ran the precheck. 👍
