672e37d040 Added .jed (programmer file) so we can build SVF or XSVF from the bitstream as needed.
Updated SVF due to "changed" .jed.
Added XSVF for future in-system programming of CPLD.

4878be8213 New .svf to reflect slew rate and IO standard changes in prior commits.
Changed name of .svf file to "default.svf" to match what ISE iMPACT wants to write out from "One Step SVF" (a.k.a. "Expresssvf").

5ab31b84e0 Remove FAST attribute from all CPLD I/O, since it changes slew rate by less than 1ns -- not enough to be important at 20MHz or so. Will re-examine later, if we try to push bus speed higher on the final board rev. 2012-07-24 12:48:08 -07:00

18587e3732 Change all IO on CPLD to LVCMOS33 until we make the move to 1V8 supplies on the MAX5864 and Si5351C. 2012-07-24 12:45:46 -07:00

9a53fd3a07 New CPLD .svf.
Change Si5351C CLK2 to 10MHz.
Keep CLK3 at 20MHz, but not inverted.
Source SGPIO8 from P1_12 instead of P9_6. (See "SGPIO Clock Routing") modification at https://github.com/mossmann/hackrf/wiki/Future-Hardware-Modifications ).

d68036f79d Eliminate ill-conceived HOST_CLK from CPLD.
Rearrange clocks to not use AC-coupled CLK1 from Si5351C.
Move CODEC_CLK to GCLK1, CODEC_X2_CLK (now HOST_CLK, too) to GCLK2.
Add trace on Jellybean PCB to connect GCLK2 to LPC4330 pin 56 (P1_12) -- a different SGPIO8.
