| * | Add flooring division operator | Xiretza | 2020-05-28 | 1 | -1/+1 |
| | | | | | | | | | | | The $div and $mod cells use truncating division semantics (rounding towards 0), as defined by e.g. Verilog. Another rounding mode, flooring (rounding towards negative infinity), can be used in e.g. VHDL. The new $divfloor cell provides this flooring division. This commit also fixes the handling of $div in opt_expr, which was previously optimized as if it was $divfloor. | ||||
| * | Add flooring modulo operator | Xiretza | 2020-05-28 | 1 | -1/+1 |

Another rounding mode, flooring (rounding towards negative infinity), can be used in e.g. VHDL. The new $modfloor cell provides this flooring modulo (also known as "remainder" in several languages, but this name is ambiguous). This commit also fixes the handling of $mod in opt_expr, which was previously optimized as if it was $modfloor. | ||||
