ImperasSC
ToolImperasSC is a RISC-V stimulus coverage tool referenced alongside ImperasFC. The available evidence describes ImperasFC/SC as tools that auto-generate SystemVerilog coverage models for RISC-V ISA features, provide detailed coverage metrics, integrate with Verdi, and support pre-RTL coverage analysis for shift-left verification.

4 connectionsImperasSC is the stimulus coverage tool that auto-generates SystemVerilog coverage models for RISC-V ISA features.
ImperasSC enables coverage analysis to begin before RTL is available, enabling a shift-left verification approach.
ImperasSC results are merged and viewed in Verdi for unified coverage reporting.
The hybrid methodology uses ImperasSC to enable pre-RTL shift-left coverage analysis.

[1] ImperasFC/SC are Functional Coverage and Stimulus Coverage tools that auto-generate SystemVerilog coverage models for RISC-V ISA features, provide detailed metrics, and integrate with Verdi. source
[2] Stimulus Coverage measures how thoroughly stimulus exercises ISA features and system behaviours, and ImperasFC/SC coverage models provide insight into coverage gaps. source
[3] ImperasSC enables pre-RTL coverage analysis and supports shift-left verification by moving validation earlier in the flow. source
