Hello, I just released InFormal 0.1.1: a new open-source assertion based verification tool. InFormal can prove the correctness of Verilog designs without using simulation -- otherwise known as formal verification. With release 0.1.1, InFormal now provides initial support for PSL/Sugar. Currently only a small subset of PSL is supported, but it's PSL never the less. Though InFormal is in very early beta, it has already uncovered bugs in real designs -- in part thanks to automatic assertions. Using InFormal's automatic assertions, engineers can find potential design issues without having to explicitly define PSL properties. InFormal leverages the elaboration and synthesis technology of Icarus Verilog with the high performance symbolic model checking engine of NuSMV. Many thanks to the Icarus and NuSMV teams for providing their awesome open-source technology.
