 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.
