| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | READ operations that can be in the extfifo pipeline. Regenerated fifo_xlnx_512x36_2clk_18to36 to include prog_full output triggered at 1017 so that there are 6 empty spaces to accept in flight read data upon completion. Had to generate the FIFO using Coregen from ISE12.1 due to 10.1 verion not working correctly in FPGA Still have to tackle making this simulate in Icarus

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | current head UHD code. Apparently operation is "flawless" but more regression and corner case regression could and should be done. Tristate drivers have been added at the top level of the hierarchy for the SRAM databus as is considered good practice for both Xilinx and ASIC design flows and so both top level and core fils have been touched.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Loopback is running via the external ZBT SRAM...HOWEVER, its not running well, its stable but the data is corrupted sometimes. Not clear if its a logic or AC timing/SI issue yet.

This puts the whole system on a 90 degree phase shift send all gpmc signals to mictor updated pins to match rev2, removed dip switch, etc. seems to compile ok. pins are different on rev2 fixed makefile to compile with our new system add register to tell host about compatibility level and which image we are using move declaration to make loopback compile no need for protocol headers since we're not doing ethernet match the signal names in this design debug pins cleanup properly integrate the new tx chain catch up with tx_policy attach run_tx and run_rx to leds connect atr delay the q channel to make the channels line up on the AD9862 ...

| | | * | | | | Added a sanity checker Python script.Nick Foster2010-08-244-3/+67
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The script just looks for input/inout/outputs that are declared in the .v but not in the .ucf. If it finds an occurrence, it aborts the compile. Removed pin "POR" from u2plus.v due to the script. Also reverted an error I introduced to test the script, which I mistakenly committed earlier.
