- high level changes: * add larger buffers on output ports * add buffers on input ports * adjust sdc file increasing output load and setting a high transition - detailed changes: * add interactive script for openlane where the order of events is a bit shuffled - to add obstruction before pdn - to manually insert buffers on some ports - to manually remove buffers inserted by synthesis on for example serial_clock_out * change openlane config adding extra row and columns to increase the space and fit the added buffers * change config to enable buffering * increase density for better placement? * change the cell exclude list. some excluded cells didn't make sense * ef decap cells break dynamic sims? * add custom pdn script for to duplicate the old pdn - misc changes: * fix openlane makefile to properly detect interactive script !important still need to run dynamic simulations !important depends on some updates to openlane |
