37 These fixes were necessary to get the SDRAM into a working simulation
capability. It is finally what it was supposed to be: cycle accurate. Sadly,
to do this, I did need to make a subtle change to rtl/wbsdram.v. (I was having
a problem with external input clocking in Verilator. This fixes it--but its
a Verilator only change--to rtl/wbsdram.v that is.)		 dgisselq 3000d 08h /xulalx25soc/trunk/rtl/
34 Bug fix: This sets as a positive voltage bias (not negative) the maximum
value of 0x07fff, where as the negative maximum value of 0x08000 properly
(now) reflects nearly ground--as one would desire. (Last time around I had
these backwards.)		 dgisselq 3004d 05h /xulalx25soc/trunk/rtl/
32 Just noticed that the timer was fixed on this. This change adjusts the
timer to support audio at a user selectable rate.		 dgisselq 3004d 07h /xulalx25soc/trunk/rtl/
31 A bug fix, although one that rearranges the bus. The first four I/O locations
have been adjusted. The new locations are reflected in wishbone.html. In
addition, the PWM and UART devices no longer create bus errors when accessed.
Finally, this version uses a `define XULA25 to determine whether or not to build
for the XuLA2-LX9 or the XuLA2-LX25. If defined, it will build for the
XuLA2-LX25. If not, for the XuLA2-LX9. The ideal location for this define
would be to place it into your Xilinx configuration, should you wish to build
for the LX25.		 dgisselq 3004d 07h /xulalx25soc/trunk/rtl/
27 Bug fix: the last_state register now correctly reflects all 5-bits of the state
machine. (Useful when detecting lockups ...)		 dgisselq 3005d 08h /xulalx25soc/trunk/rtl/
26 Some bug fixes, and the long jump early branching integration. dgisselq 3005d 08h /xulalx25soc/trunk/rtl/
23 This fixes a bug in the early branching system, and clarifies that early
branch instructions will not affect the flags. It's a basic bug fix update.		 dgisselq 3013d 18h /xulalx25soc/trunk/rtl/
21 Files, not links, to replace what were once broken links in this project. dgisselq 3066d 17h /xulalx25soc/trunk/rtl/
19 Step one in fixing soft link poblems. The following files were soft links,
and not brought into the svn repository properly. They'll be replaced in the
next update with their full sources.		 dgisselq 3066d 17h /xulalx25soc/trunk/rtl/
18 Got the bitfile back up to speed at 80 MHz. dgisselq 3070d 08h /xulalx25soc/trunk/rtl/
14 Quick bug fix. dgisselq 3072d 04h /xulalx25soc/trunk/rtl/
9 Bug fixes, optimizations, etc. as part of building for an actual hardware
implementation. Most notably, the speed was lowered from 80MHz down to
76 MHz.		 dgisselq 3072d 06h /xulalx25soc/trunk/rtl/
8 Added an interface description to the comments at the top of the file. dgisselq 3074d 16h /xulalx25soc/trunk/rtl/
7 Mostly minor changes. Fixed the legal copyright statement in the UART files,
adjusted some comments, and made sure that the zipdbg program contained all
the latest features from our Vault.		 dgisselq 3074d 16h /xulalx25soc/trunk/rtl/
6 Initial file load, likely to be buggy, but the initial load nonetheless. dgisselq 3075d 02h /xulalx25soc/trunk/rtl/
3 dgisselq 3075d 03h /xulalx25soc/trunk/rtl/
2 A very first, albeit incomplete, build. dgisselq 3075d 03h /xulalx25soc/trunk/rtl/
