I run the command ``` /home/mike/git/daveshah1/nextpnr-xilinx/nextpnr-xilinx --chipdb /home/mike/git/daveshah1/nextpnr-xilinx/xilinx/xc7a100t.bin --xdc src/queens_top.xdc --json queens.json --write queens_routed.json --fasm queens.fasm ``` but the command fails quickly with the error: ``` ERROR: Unable to place...
**Description** The runtime simulator dies unexpectedly. How can I debug this further, to determine the root cause and/or find a work-around ? Could the problem be a lack of resources...
I clone the repo, and follow the instructions in http://zipcpu.com/zipcpu/2018/01/31/cpu-build.html. Essentially, I install all the prerequisites and type `make`. The build stops with the error: ``` zipcpu/sw/binutils-2.27-zip/missing: 81: makeinfo: not...
The FPS can never get above 40. I'm using an empty skeleton shown below. I'm expecting an FPS around 100. However, in the caption the FPS rate is constantly at...
The Nexys4DDR board contains a DDR2 memory with a 16-bit data bus, and a total of 8 M words of memory. The extra memory could be used for graphics etc....
The recently added feature of fractional pixel scaling lead me to wish for a higher resolution VGA output. My first thought was whether our VHDL implementation can support such a...
This issue is about enabling fractional scaling of the display. The idea is to allow easy implementation of almost-3D games like Wolfenstein or to make smooth 3D text scrolling like...
This issue is just a placeholder for the job of porting to a new platform.
As mentioned in our last meeting, adding software emulated floating point is a first step before implementing hardware support. That way we can gauge the speed of the floating point...
