eSPI Slave SOC IIP

eSPI Slave SOC is full-featured, easy-to-use, synthesizable design, compatible with standard protocol of standard eSPI specification.Through its eSPI compatibility,it provides a simple interface to a wide range of low-cost devices.eSPI Slave SOC IIP is proven in FPGA environment.The host interface of the eSPI Slave SOC can be simple interface or can be AMBA APB, AMBA AHB, AMBA AXI, VCI, OCP, Avalon, PLB, Tilelink,Wishbone or Custom protocol.

eSPI Slave SOC IIP is supported natively in Verilog and VHDL

• Compliant with eSPI base specification as defined in Enhanced Serial Peripheral Interface (eSPI) Specification rev.1.0
• Supports Single, Dual and Quad modes
• Supports below transaction phases
• Command Phase
• Turn-Around Phase
• Response Phase
• Supports Slave triggered transaction
• Supports Power management Event
• Supports Interrupts and Alert
• Supports TX and RX operations as per specs
• Supports below multiple channels
• Peripheral Channel
• Virtual Wires Channel
• OOB Message (Tunneled SMBus) Channel
• Run-time Flash Access Channel
• Various kind of errors detection and handling
• Supports CRC checking
• The eSPI Slave SOC IP should support 2 user system bus interfaces:
• AHB-Lite
• APB
• The two interfaces should be selectable through RTL parameter and have registered input and registered output
• The Channels supported by eSPI Slave SOC will be selectable under Parameterized control
• Registers address are word (4 bytes) aligned
• Fully synthesizable
• Static synchronous design
• Positive edge clocking and no internal tri-states
• Scan test ready
• Simple interface allows easy connection to Microprocessor/Microcontroller

• Single Site license option is provided to companies designing in a single site.
• Multi Sites license option is provided to companies designing in multiple sites.
• Single Design license allows implementation of the IP Core in a single FPGA bitstream and ASIC.
• Unlimited Designs, license allows implementation of the IP Core in unlimited number of FPGA bitstreams and ASIC designs.

• The eSPI Slave SOC interface is available in Source and netlist products
• The Source product is delivered in verilog.If needed, VHDL and SystemC can also be provided
