* FIJI (+environment variable `$FIJI_ROOT` pointing to the checked-out FIJI directory)
* Configuration of Synplify in `impl/instrumented/Makefile`
## HW Setup ##
1. To control FIJI, the HX8K Breakout Board's FTDI is used. Install the following udev rule:
SUBSYSTEM=="tty",ATTRS{idVendor}=="0403",ATTRS{idProduct}=="6010",ATTRS{product}=="Lattice FTUSB Interface Cable", SYMLINK+="ttyHX8K"
2. Connect a VGA DAC to the HX8K breakout board, e.g. a XESS StickIt VGA module
The pin mappings can be found in `impl/original/tinyvga.pcf`. On the XESS
module, pin `red[3]` maps to R4, `blue[3]` to B4, etc. R0 and G0 are not
used and may be left unconnected.
## FIJI Flow ##
1. Carry out the initial synthesis step to obtain a netlist & configure
FIJI by executing
$ make fiji-instrument
$ make fiji-instrument
in `impl/original`
2. Perform the second synthesis step by running
$ make prog && make fiji-launch
$ make prog && make fiji-launch
in `impl/instrumented`
3. Inject & observe faults using the FIJI EE GUI
