Introduction

Simics provides support for writing your own PCI devices, both in DML and in C/C++.

In DML, templates are provided to make it easy to generate a PCI device and re-use the existing code to handle the configuration registers, generate PCI interrupts, etc. Section 11.2 present these templates in more details. An example of a DML PCI device is the DEC21140A model described in section 10.3.

In C or C++, Simics provides a PCI Device API defined in pci-device.h and implemented in pci-device.c. The pci-device.c provides several generic PCI device functions and interfaces to communicate with the pci-bus. There is a sample PCI device included with Simics called sample-pci-device that shows how the PCI Device API can be used. Section 11.3 provides an overview of the API. Function and type specific information can be found in the Simics Reference Manual.
