OVP Peripheral Model: NxpIMX6Uart

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.




Open Source Apache 2.0


This is an incomplete model of the UART.

It has basic functionality to support the iMX6 platform, Rx and Tx of data only.

There is no modeling of physical aspects of the UART, such as baud rates etc.

The iMX6_UART peripheral model is located in an Imperas/OVP installation at the VLNV: / peripheral / iMX6_UART / 1.0.

Peripheral Instance Parameters

This model accepts the following parameters:

Table : Peripheral Parameters

consoleboolIf specified, port number is ignored, and a console pops up automatically
clientboolIf true, model is a client and will connect to portnum. If false, model is a server and will listen on portnum.
portnumuns32If set, listen on, or connect to, this port. If set to zero in listen mode, allocate a port from the pool and listen on that.
hostnamestringName (or IP address) of host to connect to. Valid if listen=true
infilestringName of file to use for device source
outfilestringName of file to write device output
portFilestringIf portnum was specified as zero, write the port number to this file when it's known
logboolIf specified, serial output will go to simulator log
finishOnDisconnectboolIf set, disconnecting the port will cause the simulation to finish
connectnonblockingboolIf set, simulation can begin before the connection is made
xcharsuns32Width of console in characters
ycharsuns32Height of console in characters
recordstringRecord external events into this file
replaystringReplay external events from this file
