FPGA ucf files - a few corrections

Added by Conor O over 11 years ago

Hi all,

I was doing some cross referencing for my own documentation and noticed a few errors in the ucf files. This is in the last MDK so they might have been fixed. I'll also add in my own documentation in case anyone finds it useful. Especially since doing the cross correlation for the Omap-fpga was a touch tedious! If you use gawk to parse files, it can be useful to generate this stuff.

I hope these are all actual errors and not my misunderstandings but here goes....

MityDSP_L138.ucf:

o_int<0> should be LVCMOS18
o_int<1> should be LVCMOS18

i_lcs_hsync     spelling (lcd not lcs)
uhpi_hardy      spelling (hrdy not hardy)
o_vp_clkin2>    extra bracket

All the following should be LVCMOS33: 

    i_pru0r30<0 to 5 and 21>
    o_pru0r31<0 to 5>
    i_pru1r30<15 to 21>
    o_pru1r31<18 to 21>

IndustrialIO ucf file:

i_lcd_* should be LVCMOS18

io_lcd_d<?> or i_lcd_d<?> inconsistency (bit pedantic that)

Guideline docs (being very pedantic)

N8 to o_nmi_n is undocumented
uhpi_hhwl should be uhpi_hhwil
Critical_Link_FPGA_rev_C.txt (9.35 KB) Critical_Link_FPGA_rev_C.txt L138F to FPGA cross reference.
