Global Parameter
R
The following list are recommendations for bus labels:
For components that have more than one bus interface, please look at the MPD file for a
definition of listed bus interface labels. For example, the data-side OPB and instruction-
side OPB are named DOPB and IOPB, respectively.
A bus interface is assigned by name to an instance of the bus in your system.
Example
For example, the OPB bus instance is named “myopb”, and a connection to the OPB slave
interface of the OPB Uart Lite is made with the bus_interface command.
BEGIN opb_uartlite
PARAMETER HW_VER = 1.00.b
PARAMETER INSTANCE = myuartlite
PARAMETER C_HIGHADDR = 0xFFFF80FF
PARAMETER C_BASEADDR = 0xFFFF8000
BUS_INTERFACE SOPB = myopb
PORT OPB_Clk = sys_clk
PORT RX = rx1
PORT TX = tx1
PORT Interrupt = uart_intr
END
