JTAG (IEEE 1149.1/1149.6) Verification IP

JTAG (IEEE 1149.1/1149.6) Verification IP provides a smart way to verify the JTAG (IEEE 1149.1/1149.6) component of a SOC or a ASIC. The SmartDV's JTAG Verification IP works in a highly randomized manner to generate wide range of scenarios for effective verification of DUT.

JTAG Verification IP includes an extensive test suite covering most of the possible scenarios and detection of protocol violation using a effective protocol-checker.

JTAG (IEEE 1149.1/1149.6) Verification IP is supported natively in SystemVerilog, VMM, RVM, AVM, OVM, UVM, Verilog, SystemC, VERA, Specman E and non-standard verification env

JTAG (IEEE 1149.1/1149.6) Verification IP comes with optional Smart Visual Protocol Debugger (Smart ViPDebug), which is GUI based debugger to speed up debugging.
