| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Example found in the 2007.03 Liberty Reference Manual that was also found in the wild: input_voltage(CMOS) { vil : 0.3 * VDD ; vih : 0.7 * VDD ; vimin : -0.5 ; vimax : VDD + 0.5 ; } Current implementation just parses the expression but no interpretation is done. | |||||

| | * | extract_reduce: Fix segfault on "undriven" inputs | Robert Ou | 2017-09-14 | 1 | -2/+2 | |
| | | | | | | | | | | | | | | | | | This is easily triggered when un-techmapping if the technology-specific cell library isn't loaded. Outputs of technology-specific cells will be seen as inputs, and nets using those outputs will be seen as undriven. Just ignore these cells because they can't be part of a reduce chain anyways. | |||||
