Hello, I´m using it with a adder of 8 bits I found. In the scripts directory, in the openroad subdirectory there is the script that generates the file named sta.tcl, this file is in charge of listing every max and min report, the file is this one: # Copyright 2020-2022 Efabless Corporation

As you can see you can only see 5 max reports and 5 min reports, I want to show every max and min report it possible exists, but I dont know what to replace -group_count with, I already try some things I mention earlier but it didn´t work, and I know there are more because if you change 5 to 7 it shows now 7 reports, I want them all, can you help me please. |

Hello everyone, I want to be able to see every min and max report in the log directory in the sta.tcl file, but in the scripts it seems like there is a command -group_count that is not making it possible, i try different ways like not putting any number (only shows one report), removing -group_count (not working at all), and substitute with other commands like "-all_violators" or "violators_only" but it seems not working, can someone help me please.
Here is a sneak peak of min reports in the script, this file just in case is in scripts directory, in openroad subdirectory.
puts "min_report"
puts "\n==========================================================================="
puts "report_checks -path_delay min (Hold)"
puts "============================================================================"
report_checks -path_delay min -fields {slew cap input nets fanout} -format full_clock_expanded -group_count 5
puts "min_report_end"
