|===============SETUP===============
|-----Simulator Settings-----
delete_signals    | delete any existing waveforms in the window
clpr sim_out.out  | clear the output file
restart           | restart to time zero
set_mode functional

|-----Vectors-----
| Assign names to groups of related signals here.  Also, you can specify
| the radix/base in which to display these signals.

vector BUS PADXDATA[3:0]
vector READDATA READDATA[7:0]
vector WRITEDATA WRITEDATA[7:0]
vector ADDR ADDRESS[15:0]
vector PADCOM PADCOM[1:0]

|-----Watch Statements-----
| List any signals you want to see in the waveform viewer, or which you
| want to output to a file.

watch CLK BUS READDATA WRITEDATA ADDR PADCOM STROBE NEWCMD READ WRITE 
watch BUSY XBUSY ENREADDATA
watch PADXDATA[3:0]
watch RST

|-----Clock Settings----- 
| Setup various clock signals.  Also, can specify their shape and timing.
stepsize 10ns   | This gives a clock period of 20ns
clock CLK 0 1

|===============SIMULATION===============
|
| The following commands will be useful:
|   'assign' - to assign values to pins/wires (use 'release' to stop
|                driving a signal)
| We'll send the Manchester data every 64 ns (about 3 clocks)
| (Change this to between 60 and 70 ns and it still works)
