I was trying to harden one macro using openlane. Got LVS mismatches (12 net mismatches). The report is long. I found the following (suspect). Is it the cause of the LVS mismatches? How to resolve this? | Instance: sky130_fd_sc_hd__buf_12:repeater | (no matching instance) A = 3 | VGND = 399 | VNB = 399 | VPB = 399 | VPWR = 399 | X = 6 | | Instance: sky130_fd_sc_hd__buf_12:repeater | (no matching instance) A = 6 | VGND = 399 | VNB = 399 | VPB = 399 | VPWR = 399 | X = 5 | ---------------------------------------------------------------------------------------

Can you upload the entire report?

Here is the full log.

First thing I noticed is that your sram pins aren't matching.

Subcircuit pins:

vssd1                                      |vssd1                                      
(no matching pin)                          |wmask0                                     
csb1                                       |(no matching pin)                          
clk1                                       |(no matching pin)                          
wmask0[0]                                  |(no matching pin)

I'd change the layout

wmask0[0]

to

wmask0

and add

csb1

and

clk1

to the verilog stub. (These should probably be grounded if unused instead of being left unconnected). Next you can see that your sram macros are not connected to power.
