@ -74,11 +74,18 @@ mid-term (6 months):
- inter-tile wire connections (model_conns.c)
- configure devices and route wires
cleanup (whenever convenient):
* use tile flags instead of tile names
* model connections and switches together rather than separately
* describe more wire names/meanings with integers instead of strings
* move all part-specific static data into xc_info()
long-term (>6 months):
* auto-crc calculation in .bit file
* support lm32 or openrisc core, either via libfpga or iverilog backend
* ipv6 or vnc in hardware?
* iverilog fpga backend
* design fpga 'core' that uses high-speed icap/reconfig to process data
