Eh. Typical low end CPLD. Probably the worst soldering job I've ever seen in my life on the through hole components. Surface mount stuff was okay but it looks like someone blind soldered the headers and stuff. Tons of flux residue and corrosion and cold solder joints and overall cheap components. Board layout is decent overall but the headers are useless if you wanted to connect a ribbon cable to them because they each header only has a couple grounds. Many grounds are necessary for high speed communication via ribbon cable to keep low capacitance and stuff. Pretty useless board honestly. But it works so I guess it would be good for someone learning vlsi design. Board layout does not facilitate use of differential signaling (differential pairs of traces on board not present)
