CPLD or FPGA?
The main difference is that CPLDs are smaller than FPGAs, i.e. you can fit a lot more logic inside a FPGA than inside a CPLD.
- CPLDs: address decoders, bus interfaces, simple memory controllers, (video) signal generators
- FPGAs: complex CPUs, high speed I/O, signal processing, encryption
VHDL or Verilog?
The difference is mainly in syntax, you can get the same synthesis result with both languages. VHDL is more verbose than Verilog (which can be an advantage or disadvantage, depending on how you look at it). In Europe VHDL is much more widely used than Verilog, in the US Verilog seems to be slightly more popular.
