Gold standard for SD CARD memory device and SD Host Controller for your IP, SoC, and system-level design verification.

In production since 2012 for many production designs.

SD CARD Cadence Verification IP (VIP) upgrades the SD CARD and SDIO verification platform with Ultra High Speed Type II (UHS-II) support. It allows seamless verification of legacy SD CARD and SDIO protocol (version 3.00 and below) and the latest UHS-II interface. The UHS-II interface allows access to traditional SD CARD and SDIO applications through the SD-TRAN layer and to the UHS-II memory space through the CM-TRAN layer. The VIP allows full-stack UHS-II interface verification (TRAN + LINK + PHY) through the serial interface and protocol IP verification (stripped of PHY) through the PHY-LINK I/F defined in the specification.

SD Host Controller Cadence Verification IP (VIP) is based on Part E1 SDIO (SD input/output) specification defined for SD and SPI bus interface specification for SDIO including register specification. It is defined for SDIO Card, Embedded SDIO device, and Combo Card.

Supported specifications:

For SD CAR – Part 1 Physical Layer Specification Version 4.00 and Part 1 UHS-II Addendum Version 1.00
For SD Host Controller – SD Specifications Part E1 SDIO Simplified Specification Version 3.00 and Part 1 Physical Layer Specification Version 3.01.

Product Highlights

  • Hundreds of protocol and timing checkers to easily catch design bugs
  • Hundreds of predefined configurations based on specific memory vendors' part numbers, datasheets, or generic JEDEC definitions available on ememory.com
  • Transaction and memory callbacks for all protocol, model states, and device memory events
  • Error injection capability through user modification of transaction contents
  • Ability to check for errors and change error severity
  • Callback events for packets at entry/exit of LINK layer and Transaction layer on the receive and transmit sides
  • Callback events at PHY layer to monitor bus activity and to inject errors
  • Ability to dynamically change configuration parameters
  • Packet tracker creation for easy debugging
  • Support testbench language interfaces for SystemVerilog and UVM
