7b33ff0405 Fixing yet another fifo bug... 2020-03-20 20:39:15 -04:00
Andreas.Olofsson
3c8be0c083 Fixing brain-dead bug! 
-I guess nobody has been using this fifo, because it was hoplessly broken. Fucking sad.

bee941aa61 Adding reset wakup event to standby module 
-Create an event at rising edge of reset
-Turn on the clock for long enough to allow for reset signal to get turned on
-Note the race here! This is why the rest and standby needs to be combined into one block.

412fb61519 Changing delay function to take a clock 
-The combinatorial delay elemement doesn't belong in this library, too specific!

04675f49a7 Adding synchronous clear signal to fifo 
-It's not uncommon to want to clear/invalidate all entries int he FIFO
-Still need async reset for power-on in absence of clocks

9e9d323025 Changing the CFG_ASIC approach 
-Should be ifdef, since this is a global. You will never be doing and not an asic at the same time!

7094173ae9 Reorg! Why? 
- The top level directory was not scaling, too imposing
- Friendlier to download a repo and see a finite number of top level dirs
- We are just getting started...

3ae9c26d38 Changing shift/load order 
- Load should always have higher priority, but load is blocked if there is a pending shift anyway...

da6856befa Adding reset signal to pulse interfaces 
- Needed for some logic with feedback, otherwise you get "x" loop
- Those who don't need it should be able to connect nrest to 1'b1

8c350eed91 Debugged most of SPI 
-Changed to FIFO on TX path (cleaner)
-No good solution on RX with CDC since clock can stop, so you can't use an async fifo.
-Slave needs cleanup, rethink...
-Using commong par2ser and ser2par blocks
