Avery Design Systems Introduces SCSI-Xactor Verification IP for PCIe-based SSD

Avery Design Systems recently introduced their SCSI-Xactor verification IP. SCSI-Xactor targets SCSI Express for high performance PCIe-based SSDs. Avery’s verification IP is a complete solution for SCSI Express core and system design. SCSI-Xactor helps design and verification engineers to quickly and extensively test the functionality of SCSI Express controller-based designs.

SCSI-Xactor works in conjunction with Avery’s PCI-Xactor PCI Express Verification IP solution. A SCSI Express bus adaptor layer enables the SCSI Express host software BFM to hook up to any bus interface such as PCIe and AMBA AXI and enables running the SCSI Express host software BFM with or without the PCIe root complex and endpoint IP stacks yielding faster simulation performance for large data movement in both SCSI Express core-level and SOC-level verification environments. A reference SCSI Express controller supports core-level verification by emulating the NAND Flash backend subsystem.

SCSI-Xactor Solution

  • SCSI Express host software BFM
  • SCSI Express host and controller bus adaptor
  • Reference SCSI Express controller and adaptor for emulating SCSI targets
  • Producer-consumer scoreboard
  • Compliance test suite
  • Comprehensive protocol checks
  • Protocol analyzer tracker
  • Functional coverage model
  • Works with any PCIe and AXI IP or VIP

SCSI-Xactor is based on the standards work of INCITS T10′s SOP-PQI Working group and the SCSI Trade Association. The protocol is based on the SCSI over PCIe (SOP) host interface specification, which enables SCSI initiators communicating to SCSI targets over PCIe through the PQI transfer layer. The new protocol will enable SCSI devices to utilize the faster PCIe transport required to meet the demand in next generation enterprise designs.
