#36 opensta report units Issue opened by SweeperAA The opensta.min_max.rpt file seems to show min and max slack data. What units are being used in this report? For example, my opensta.min_max.rpt has:

...

2.00 12.00 clock vclk (rise edge)

0.00 12.00 clock network delay (ideal)

0.00 12.00 clock reconvergence pessimism

12.00 ^ _35045_/CLK (sky130_fd_sc_hd__dfxtp_4)

-0.09 11.91 library setup time

11.91 data required time

11.91 data required time

-11.08 data arrival time

0.83 slack (MET)

I would have guessed that these are in ns, but my .tcl and .sdc files specify 10ns clock periods: config.tcl

set ::env(CLOCK_PERIOD) "10.0"

sky130A_sky130_fd_sc_hd_config.tcl

set ::env(CLOCK_PERIOD) "10.000"

project.sdc

set_units -time ns create_clock [get_ports clk] -name core_clock -period 10
