The ATCUART100 peripheral model is located in an Imperas/OVP installation at the VLNV: / peripheral / ATCUART100 / 1.0.

Peripheral Instance Parameters

This model accepts the following parameters:

Table : Peripheral Parameters

finishOnDisconnectboolIf set, disconnecting the port will cause the simulation to finish
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
consoleboolIf specified, port number is ignored, and a console pops up automatically
portnumuns32If set, listen on this port. If set to zero, allocate a port from the pool and listen on that.
infilestringName of file to use for device source
charmodeboolDescription Set to true when the port is used to connect to a Telnet program and character mode is desired rather than the default Telnet line mode. When set to true a Telnet command sequence is sent at startup that configures the Telnet program into character mode. In addition null bytes are stripped from the data received.
simulatebaudboolDescription Set to true to simulate baud delay determined by the Divisor Latch register value and reference clock frequency. Set to false to run without delay - next read data is made available immediately upon read of Receiver Buffer Register. Defaults to false
refClkFrequns32Frequency (in hertz) of reference clock rate used in baud rate calculation
fifoSizeuns32Size of fifos
uart16450boolRun in 16450 mode (no FIFOs)
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
