OVP Peripheral Model: Amd79C970



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.

Licensing

Open Source Apache 2.0

Description

Implements part of the AMD AM79C97xx series Ethernet devices.

diagnosticlevel: bits 0:1 give levels for the network hardware. bits 2:3 give levels for the user:mode SLIRP interface.

Limitations

Sufficient is implemented to Boot MIPS Linux and support ethernet TCP/IP services.

Reference

AMD Am79C973/Am79C975 PCnet-FAST III Single-Chip 10/100 Mbps PCI Ethernet Controller with Integrated PHY Datasheet

Location

The 79C970 peripheral model is located in an Imperas/OVP installation at the VLNV: amd.ovpworld.org / peripheral / 79C970 / 1.0.



Peripheral Instance Parameters

This model accepts the following parameters:

Table : Peripheral Parameters

NameTypeDescription
PCIslotuns32Set the PCI slot at which the Ethernet card is installed
PCIfunctionuns32Set the PCI function of the device. The default of 0 is correct for this device.
newbool
MACuns64Set the MAC address of the NIC, as read from the PCI bus. Note that the interface to the host's network is at the TCP/UPD level so it is not possible to affect the actual MAC address. Example: ab:cd:ef:01:23:45
tapDevicestringThe name of the TAP device
redirstringUser mode redirection of host port to virtual port (using SLiRP), command format <protocol>:<host port>:<ip address>:<virtual port>
tftpPrefixstringPath to the root of the tftp directory
networkstringThe (v4) IP address of the local network device.
logfilestringThe file to which Ethernet frames should be logged. Uses pcap file format, viewable by Wireshark and other programs
recordstringRecord external events into this file
replaystringReplay external events from this file
