Merge pull request #1094 from mkj/matt/sim-regular-comb 
litex_sim: Allow regular_comb=False argument
 2021-11-02 15:04:42 +01:00
Matt Johnston 1716e37809 litex_sim: Allow regular_comb=False argument 
This was removed in
3b78fd928d fhdl/verilog: Remove blocking_assign (not used with LiteX).

However that breaks litedram gen.py which passes regular_comb=False
to all toolchain builders

Florent Kermarrec 296688b2d8 cores/jtag/ECP5JTAG: Fix LUT4's INIT to create a buffer instead of inverter, thanks @gregdavill. 
Avoid restriction to even number for tck_delay_luts.
 2021-10-27 11:01:09 +02:00
Florent Kermarrec 0b40d78b0d cores/jtag/ECP5JTAG: Delay TCK with LUT4 to avoid sys_clk/jtag_clk relationship and support higher jtag_clk frequencies. 
Tested succesfully on the ButterStick with 75MHz sys_clk/25MHz jtag_clk.

Current tck_delay_luts is abritrary and should probably be adjusted.

Florent Kermarrec 9b4c7e8288 README/litex_setup: Remove reference to LiteVideo to encourage use of LiteX's VideoTerminal/Out core. 
LiteVideo is not longer maintained, does not have CI and is messy (code is ~10 years old where we were
still experimenting the innovative approach with Migen). The core is kept since can be useful as reference
for Video Input and for projects using it but it is not recommended for new designs.
