d0171fd1d8 Adding ASIC interface to single port memory 
- Yes, I know this means more signals for others to "ignore". The fpga way to handle this is to auto generate hierarchy to hide the signals.
- I prefer a flatter structure with signals tied off and a library of known good components in a repo!

2a22cd6ff8 Removing delay + clock gating 
- delay could hide bad designs..
- clock gating was hard to handle from outside

ddfb4e00de Fixing generic fifo 
- This one is looking better
- Still needs more review. At least now it has a testbench...

cdef6141b4 Adding 2nd clock to interface 
- Randomizeing clock frequencies
- Phase and frequency randomization a must for catching first order sync problems (and debunking really stupid ideas...)
- Don't be clever, be smart!

fc7dc0e70a Adding "SEED" as basic parameter 
-making randomness clocks a first class citizen
-Verilog doesn't have a seed, need to drive it from the shell
-a must for async clocks, useful for many things
-does not preclude randomization externally as well

bb4a602f7f New "dut files" 
- new clocks (clk1 and 2)
- simpler names
- fifo dut

852d7da490 Adding generic target 
- all sims should have a "cfg file"
- since everything is configurable, this is the easiest way

5c66c16714 Reorg: moving generic fifo to separate file 
- design was too "xilinx centric" before.
- library should work in any technology

fd7aff5dd8 Fixing warning messages in chip synthesis tool 
- Don't fight the tools
- No way to remove these warnings and I don't want to have to tell everyone to include maging "don't output this kind of warning flags" that are global to a project...that's just bad practice.
- Didn't take many minutes to remove these warnings and now synthesis runs through with 0 warnings ... much cleaner.. inspires more confidence
