lvs.log

Hi,

I have LVS errors in the precheck.

I checked the report and log files. As far as I understand, sky130 FFs cause some mismatch:

sky130_fd_sc_hd__dfxtp_1
sky130_fd_sc_hd__dfrtp_1

I attached precheck LVS related log and report files. The design has 195 macro instantiations in the wrapper and only pin connections

Thanks

Looks like you haven't included all macros inside your design

These are the macros not included:
```cby_1__1_ is a black box in the source
cbx_1__6_ is a black box in the source
sb_6__0_ is a black box in the source
grid_clb is a black box in the source
cbx_1__1_ is a black box in the source
grid_io_top is a black box in the source
sb_1__6_ is a black box in the source
cbx_1__0_ is a black box in the source
sb_1__1_ is a black box in the source
grid_io_bottom is a black box in the source
sb_1__0_ is a black box in the source
grid_io_right is a black box in the source
cby_0__1_ is a black box in the source
cby_6__1_ is a black box in the source
sb_0__6_ is a black box in the source
grid_io_left is a black box in the source
sb_0__1_ is a black box in the source
constant_assignments is a black box in the source
sb_6__6_ is a black box in the source
sb_0__0_ is a black box in the source
sb_6__1_ is a black box in the source```
To do so, you can point to them in `lvs/user_project_wrapper/lvs_config.json` file

Thanks <@U024X6E1QG5>

I am not familiar with lvs_config

So I have to add them only in LVS_VERILOG_FILES in lvs_config right?

Yes, you can find the documentation here <https://github.com/efabless/mpw_precheck/blob/main/checks/be_checks/README.md>
