This leon3 design is tailored to the Digilent Spartan3-1600E Evaluation board:
http://www.digilentinc.com/Products/Detail.cfm?Prod=S3E1600&Nav1=Products&Nav2=Programmable
Design specifics:
* System reset is mapped to SW_SOUTH (reset)
* DSU break is mapped to SW_EAST
* LED 0/1 indicates console UART RX and TX activity.
* LED 2/3 indicates DSU UART RX and TX activity.
* LED 4 indicates processor in debug mode
* LED 7 indicates processor in error mode
* The GRETH core is enabled and runs without problems at 100 Mbit.
Ethernet debug link is enabled, default IP is 192.168.0.51.
* 16-bit flash prom can be read at address 0. It can be programmed
with GRMON version 1.1.16 or later.
* DDR is mapped at address 0x40000000 (64 Mbyte) and is clocked
at 100 MHz. The processor and AMBA system runs on a different
clock, and can typically reach 40 MHz. The processor clock
is generated from the 50 MHz clock oscillator, scaled with the
DCM factors (4/5) in xconfig.
* The APBPS2 PS/2 core is attached to the PS/2 connector
* The SVGA frame buffer runs fine with 800x600 resolution. Due to the
limited number of clock buffers, no other resoltion is supported.
Note that the board does not have a video DAC, so only the MSB bit (7)
of the three colour channels is connected to the VGA connector.
A test patter can be generated using grmon-1.1.18 or later with:
draw test_screen 800 16
* The DSU uart is connected to the female RS232 connected.
The application UART1 is connected to the male RS232 connector.
* The JTAG DSU interface is enabled.
* Output from GRMON info sys is:
ethernet startup.
