| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A typical use of `bugpoint` would involve a script with a pass under test, e.g.: flowmap -relax -optarea 100 and would be invoked as: bugpoint -yosys ./yosys -script flowmap.ys -clean -cells This replaces the current design with the minimal design that still crashes the `flowmap.ys` script. `bugpoint` can also be used to perform generic design minimization using `select`, e.g. the following script: select i:* %x t:$_MUX_ %i -assert-max 0 would remove all parts of the design except for an unbroken path from an input to an output port that goes through exactly one $_MUX_ cell. (The condition is inverted.) | |||||

| | * | | | opt_expr: improve simplification of comparisons with large constants. | whitequark | 2019-01-02 | 1 | -70/+47 | |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The idea behind this simplification is that a N-bit signal X being compared with an M-bit constant where M>N and the constant has Nth or higher bit set, it either always succeeds or always fails. However, the existing implementation only worked with one-hot signals for some reason. It also printed incorrect messages. This commit adjusts the simplification to have as much power as possible, and fixes other bugs. | |||||

| | * | | | opt_expr: simplify any unsigned comparisons with all-0 and all-1. | whitequark | 2019-01-02 | 1 | -17/+69 | |
| | | | | | | | | | | | | | | | | | | | | | | | | | Before this commit, only unsigned comparisons with all-0 would be simplified. This commit also makes the code handling such comparisons to be more rigorous and not abort on unexpected input. | |||||
