SWD(Serial Wire Debug) Verification IP provides an efficient and simple way to debug and trace functionality on processor cores and System on Chip (SoC) devices. The SmartDV's SWD Verification IP is fully compliant with ARM Serial Wire Debug interface Specification and provides the following features.
SWD Verification IP is supported natively in SystemVerilog, VMM, RVM, AVM, OVM, UVM, Verilog, SystemC, VERA, Specman E and non-standard verification env
SWD Verification IP comes with optional Smart Visual Protocol Debugger (Smart ViPDebug), which is GUI based debugger to speed up debugging.
