Avery Design Systems Announces SymXprop for X Accurate RTL Simulation

TEWKSBURY, MA., May 30, 2019 – Avery Design Systems Inc., an innovator in functional verification productivity solutions, today announced availability of SymXprop that performs high accuracy semi-formal based RTL X handling to eliminate the inherent inaccuracies in logic simulators.

“Design practices involving partial reset, uninitialized memories, and clock and power gating expose SystemVerilog’s inaccurate RTL X handling semantics by creating X-optimism and X-pessimism issues in RTL simulations and result in extra engineering time needed to effectively debug and work around the issues,” said Chris Browy, VP Sales/Marketing. SymXprop analyzes X propagations in RTL simulations for combinatorial and sequential X inaccuracies using patent pending hybrid formal analysis and automatically eliminates these X inaccuracies in RTL simulations.

Highlights of the new SymXprop solution:
• Analysis modes for X-optimism and X-pessimism
• Scalable to large designs with built-in distributed parallel processing
• Analyze one or multiple submodules displaying X issues
• Supports VCS, Xcelium, and Questa simulators
