SDIO 4.20 VIP

SDIO 1.0, 2.0,3.0 and 4.20 VIP is an advanced solution in the market for the verification of SDIO 1.0/2.0/3.0/4.20 implementations. It is adherent with SDIO 1.0/2.0/3.0/4.20 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 specification.

SDIO 1.0/2.0/3.0/4.20 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 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 4.20 VIP is supported natively in SystemVerilog, VMM, RVM, AVM, OVM, UVM, Verilog, SystemC, VERA, Specman E and non-standard verification env
