Mentor Graphics Modelsim Se-64 10.7 Free Jun 2026

For a small to medium-sized team working on a Xilinx Zynq or Intel Arria 10 design, ModelSim SE 10.7 is more than sufficient and significantly cheaper than upgrading to Questa.

ModelSim SE 10.7 processes inline assertions to validate protocol compliance in real time. If a bus protocol violation occurs (e.g., an illegal state transition on a PCIe or AXI bus), the simulator flags the exact simulation timestamp, instantly isolating transient hardware bugs.

Gate-level sims often produce 'X'. Use the -no_async_delay flag during SDF annotation to reduce pessimistic X states. For a small to medium-sized team working on
