MiSTer to MiST procedure

• Use the templates:
  • CORE-template_poseidon-ep4cgx150.qsf
  • CORE_top-template.sv
  • files-template.qip

Steps to generate core_top.sv module

• The first thing to do is after adding comments to the HDMI stuff is to also put comments to hps_io.
• Disable anything hdmi related
• To get video signal check if there is a video mixer first on MiSTer core
• Whatever is in video mixer should usually go to mist_video
• Rename the clock: CLOCK_50 (poseidon MiST board) vs CLK_50M (MiSTer)
• The SDRAM_CLK assigned to negative clk signal.
• Move the proper signals on hps_io module call to user_io
• Adapt files.qip changing MiSTer to MiST framework modules (mist-modules)

// the top file should generate the correct clocks for the machine

`ifdef INVERT_SDRAM_CLOCK
	assign SDRAM_CLK = ~clk_sys;
`else
	assign SDRAM_CLK = clk_sys;
`endif

pll pll(
`ifdef CLOCK_IN_50
	.inclk0	( CLOCK_50		),
`else
	.inclk0	( CLOCK_27		),
`endif
	.c0     ( clk_sys		),
	.locked	( pll_ready		)  // pll locked output
);

NOTES:

• If still you don't get a video it has to be either a RAM issue or it needs some adjustments to get the proper VSync and/or HSync.
• If it is a RAM issue... good luck then that's my todo list most of the times.

MiST Modules

• osd.v
• scandoubler.v
• data_io.v
• user_io.v
• sdram.v

user_io.v -> user_io.v  

video  
video_mixer -> mist_video.v
