Hi All, this questions is about the characterization of cell library using Liberate 16.
1. When characterizing a custom made cell using ccs model, do we need to still provide slew/capacitive load combinations in the tcl files ? Or does ccs automatically find the slew values corresponds to specified load by simulations (suppose I use spectre as the external simulator) ?
2. For the re-characterization of a cell library for low voltage operation, can we use the tcl file generated by Liberate from the existing .lib file ? So here my concerns is again about the slew/load combinations in the existing lib. Shouldn't slew values be updated by doing simulations by our-self ? Or liberate does it self ?
Thanks in advance
