## Expected Behavior https://antmicro-skywater-pdk-docs.readthedocs.io/en/test-submodules-in-rtd/contents/libraries/foundry-provided.html has pages for each stdcell variant but sky130_fd_sc_lp under PDK Contents/Libraries. ## Actual Behavior sky130_fd_sc_lp has a page like https://antmicro-skywater-pdk-docs.readthedocs.io/en/test-submodules-in-rtd/contents/libraries/sky130_fd_sc_hd/README.html ## Steps to Reproduce the Problem...

pins are mis-modelled in LEF

9

## Expected Behavior The pins is LEF are misusing the PORT statement. To pick a specific example (there are many others) look at MACRO sky130_fd_sc_hd__dfbbn_1 PIN SET_B [here](https://github.com/google/skywater-pdk-libs-sky130_fd_sc_hd/blob/ac7fb61f06e6470b94e8afdf7c25268f62fbd7b1/cells/dfbbn/sky130_fd_sc_hd__dfbbn_1.lef#L68) In the...

suspicious buf max_capacitance values

2

In examining sky130_fd_sc_hd__tt_025C_1v80.lib I see: cell ("sky130_fd_sc_hd__buf_1") { max_capacitance : 0.1300150000; cell ("sky130_fd_sc_hd__buf_2") { max_capacitance : 0.3158670000; cell ("sky130_fd_sc_hd__buf_4") { max_capacitance : 0.5612280000; cell ("sky130_fd_sc_hd__buf_6") { max_capacitance : 0.7855320000; cell...

sky130 antenna cell has the wrong type

3

The discussion in https://github.com/The-OpenROAD-Project/OpenROAD/pull/2136 highlights that ``` MACRO sky130_fd_sc_hd__diode_2 CLASS CORE ; ``` is incorrect and should be ``` MACRO sky130_fd_sc_hd__diode_2 CLASS CORE ANTENNACELL ; ``` Since I can't get...

Put biggest buffer 1st in CTS_CLK_BUFFER_LIST

2

In sky130/openlane/sky130_fd_sc_hd/config.tcl you have: ```set ::env(CTS_CLK_BUFFER_LIST) "sky130_fd_sc_hd__clkbuf_2 sky130_fd_sc_hd__clkbuf_4 sky130_fd_sc_hd__clkbuf_8"``` it is currently better to put the largest buffer first like: ```set ::env(CTS_CLK_BUFFER_LIST) "sky130_fd_sc_hd__clkbuf_8 sky130_fd_sc_hd__clkbuf_4 sky130_fd_sc_hd__clkbuf_2"``` OR will eventually not care...
