T2M Verification IPs I2C VIP


Description and Features

I2C Verification IP provides a smart way to verify the I2C bi-directional two-wire bus. The I2C Verification IP is fully compliant with version 2.1, 3.0 and 6.0 of the Philip's I2C-Bus Specification and provides the following features. It is supported natively in SystemVerilog, VMM, RVM, AVM, OVM, UVM, Verilog, SystemC, VERA, Specman E and non-standard verification env I2C Verification IP comes with optional Smart Visual Protocol Debugger which is GUI based debugger to speed up debugging.
