Exhaustive Verification

Automated memory-mapped register verification

The Questa Register Check app is a fully automated solution for exhaustively verifying control&status register behavior against your CSV or IP-XACT register specification. No knowledge of formal or property specification languages is required.

Ensure coverage of the state space

The Devil in the Details

Even relatively small IPs can have hundreds of control&status registers, many with unconventional access policies. While testbench simulation-based register verification approaches like UVM_REG can exercise most of the primary use cases, numerous corner-cases are left uncovered, creating the risk of show stopper bugs going undetected.

Front- & back-door register access

Exhaustive verification of control & status registers

The Questa Register Check app automates exhaustive verification of control and status registers. Taking your register spec (in CSV or IP-XACT) and RTL as input, the app automatically derives the properties and runs the formal engines under-the-hood. Any discrepancies in register behavior are graphically shown in detailed waveforms.
