39 An attempt at a bugfix. We'll see if this works any better downstream. dgisselq 3031d 02h /xulalx25soc/trunk/rtl/
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 3031d 23h /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 3035d 20h /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 3035d 22h /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 3035d 22h /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 3036d 23h /xulalx25soc/trunk/rtl/
26 Some bug fixes, and the long jump early branching integration. dgisselq 3036d 23h /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 3045d 09h /xulalx25soc/trunk/rtl/
21 Files, not links, to replace what were once broken links in this project. dgisselq 3098d 08h /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 3098d 08h /xulalx25soc/trunk/rtl/
18 Got the bitfile back up to speed at 80 MHz. dgisselq 3101d 23h /xulalx25soc/trunk/rtl/
14 Quick bug fix. dgisselq 3103d 19h /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 3103d 21h /xulalx25soc/trunk/rtl/
8 Added an interface description to the comments at the top of the file. dgisselq 3106d 07h /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 3106d 07h /xulalx25soc/trunk/rtl/
6 Initial file load, likely to be buggy, but the initial load nonetheless. dgisselq 3106d 17h /xulalx25soc/trunk/rtl/
3 dgisselq 3106d 18h /xulalx25soc/trunk/rtl/
2 A very first, albeit incomplete, build. dgisselq 3106d 18h /xulalx25soc/trunk/rtl/
