Mentor, a Siemens business, is pleased to announce the availability of QuestaSim 2021.1 comprehensive platform for verification complex designs. Questa is built on a core simulation and debug engine providing the industry's most complete native support of Verilog, SystemVerilog, VHDL, SystemC, PSL and UPF.

General Defects Repaired in 2021.1
QSIM-55060 - Running vopt to re-generate an existing optimized design after the work library had been moved in the file system would sometimes produce an error message involving the original file pathnames. The behavior has been fixed, and vopt will now re-generate the optimized design.
QSIM-68141 - (results) Some VCD files contain extended (VHDL) identifiers. The vcd2wlf and vcd2qwave tools did not always read these identifiers correctly. This has been corrected.

SystemVerilog Defects Repaired in 2021.1
QSIM-62161 - (results) In some rare cases, randomize() would incorrectly evaluate a constraint involving a dist/inside/unique construct with an indexed multi-dimensional array (where the index is random) on the RHS. This issue has been fixed.
QSIM-62470 - In some rare cases, a randomize() call with an in-line constraint that references a static class field would cause vo

Power Aware Enhancements in 2021.1
QSIM-56976 - Enhanced the waiver mechanism / exclusion support for PA dynamic Checks. More ways to control the PA dynamic checks at vopt/vsim.

QuestaSimis part of the Questa Advanced Functional Verification Platform and is the latest tool in Mentor Graphics tool suite for Functional Verification. The tool provides simulation support for latest standards of SystemC, SystemVerilog, Verilog 2001 standard and VHDL. This tool is an advancement over Modelsim in its support for advanced Verification features like coverage databases, coverage driven verification, working with assertions, SystemVerilog constrained-random functionality.
