SmartDV’s SWD Verification IP is a comprehensive solution for verifying the ARM Serial Wire Debug interface, the two-pin low-pin-count alternative to JTAG used for accessing debug and trace resources on ARM-based systems-on-chip. Fully compliant with the ARM Debug Interface Architecture Specification ADIv6.0 and backward compatible with ADIv5.0 through ADIv5.2, it supports complete verification of SWD Host and Device components across a single bidirectional SWDIO data connection with separate SWCLK clock, synchronous data transfer, START and STOP bit generation and handling, Debug Port (DP) and Access Port (AP) register accessing, and multidrop SWD supporting multiple Debug Ports on a single bus as introduced in ADIv6.
SmartDV’s SWD VIP supports UVM, SystemVerilog, and Verilog, and integrates seamlessly into diverse verification environments. It is simulator-independent and compatible with all leading EDA simulators, providing flexibility across simulation platforms.
With WAIT and FAULT response handling, Line Reset, Header and Data parity generation and checking, Sticky Overrun behavior, SW-DP write buffering, comprehensive error injection, built-in functional coverage, and a complete test suite, SmartDV’s SWD VIP enables verification teams to thoroughly validate SWD interface designs for ARM-based microcontrollers, application processors, debug probes, and any SoC requiring low-pin-count on-chip debug and trace access.
