OVP Peripheral Model: XilinxZynq7000Qspi

Model Specific Information

This page provides introductory usage information for an Imperas OVP peripheral behavioral model. The page is split into sections providing specific information for this peripheral, including any ports for connecting into a platform, registers, other component parts, and configuration options and general information for peripheral modeling with Imperas OVP.


Zynq 7000 Quad-SPI Registers and incorporates Flash Memory (Spansion and Micron) for Zync zc702/zc706 boards


Open Source Apache 2.0


This model implements the full set of registers but not all flash memory accesses are supported.

The model is tested using Xilinx Example Project for R/W a QPSI memory on ZC702 platform using Polled and Interrupt driven Transfers.

The AXI mode of operation is not tested. There is no write protection implemented for memory access when in AXI mode.


Zynq-7000 TRM (


The zynq_7000-qspi peripheral model is located in an Imperas/OVP installation at the VLNV: / peripheral / zynq_7000-qspi / 1.0.

Peripheral Instance Parameters

This model accepts the following parameters:

Table : Peripheral Parameters

imagestringSpecify a file to initialize flash memory. String of form <file>[@<offset>]
imageoutstringSpecify a file to write the flash memory at the end of simulation. String of form <file>[@<offset>][:<size>]
flashstringDescription Specify the type of flash memory, 'spansion' or 'micron' (default) Limitations The Spansion Flash memory device is not tested. The Micron flash memory device is tested using the Xilinx example program.
