This resulted in hard to use tools. With ver 2.0.0 we significantly simplified our command language by 2-5X while increasing its robustness. Ver 3.0.0's gate-level option takes an even greater step forward. Simplex doesn't do power consumption analysis. This is true.
Run times are long.
Although run times have been reduced by 5X-10X from ver 1.2.3. 3.0.0's gate-level option incorporates a revolutionary technology to address the need for faster cycle times, larger capacity and better accuracy. Simplex does support multi-voltage design. Our tools make no assumptions as to the number of power supplies on a chip or their voltage. Our users often have chips with 3 or more power supplies at 3 voltage levels.
