Yet another digital clock

The classic *nix first program is one that prints "Hello world" on the console. For me, my first project seems to be a digital clock. I made one when I started experimenting with Microchip PICs in 1999. A few years back I made one using my Verilog emulation of an Intel 4004, So it made sense to make one as my first project using the PicoBlaze soft processor.

After recording this video I left it running overnight. The next morning, to my consternation, I found it had stopped with the display showing. 11:01:12.

Running Xilinx ChipScope under Ubuntu

I've belatedly realized that ChipScope Pro is a free feature of Xilinx ISE 14.7. While trying a simple example I ran into two problems, both of which I have managed to work around.

Xilinx firmware download problems

I've discovered an error in my post Making Xilinx ISE iMPACT 14.7 run on Ubuntu 20.04. I've corrected the error, and added a note explaining that a previous version contained an error.
