SDIO 8.0 Verification IP

Overview

SDIO 1.0, 2.0,3.0,4.20,5.0,5.10,6.0,6.10,7.0,7.10 and 8.0(Draft) VIP is an advanced solution in the market for the verification of SDIO 1.0/2.0/3.0/4.20/5.0/5.10/6.0/6.10/7.0/7.10/8.0(Draft) implementations. It is adherent with SDIO 1.0/2.0/3.0/4.20/5.0/5.10/6.0/6.10/7.0/7.10/8.0(Draft) VIP and it supports SPI, SD1, SD4 and MMC8. It can generate all command types. The SDIO VIP monitor acts as powerful protocol-checker, fully compliant with SDIO 1.0/2.0/3.0/4.20/5.0/5.10/6.0/6.10/7.0/7.10/8.0(Draft) specification.

SDIO 1.0/2.0/3.0/4.20/5.0/5.10/6.0/6.10/7.0/7.10/8.0(Draft) VIP includes an extensive test suite covering most of the possible scenarios and SDIO conformance norms. SDIO 1.0/2.0/3.0/4.20/5.0/5.10/6.0/6.10/7.0/7.10/8.0(Draft) VIP can perform all protocol tests as testbench and moreover it allows an easy generation of a very high number of patterns and a set of specified patterns to stress the DUT.

SDIO 8.0 Verification IP is supported natively in SystemVerilog, VMM, RVM, AVM, OVM, UVM, Verilog, SystemC, VERA, Specman E and non-standard verification env

SDIO 8.0 Verification IP comes with optional Smart Visual Protocol Debugger (Smart ViPDebug), which is GUI based debugger to speed up debugging.
