Generally vendors who provide development boards with FPGAs provide some PCB design guidelines related to the FPGA. For e.g. Digilent has some PCB layout recommendations for the Xilinx part used in that dev board.
So have you search the vendor's website who provide/sell Altera based dev boards?
Unless you have extreme temperature conditions or unusual high power dissipation (e.g. operating many logic cells at high clock frequency) there's np specific problem with thermal performance of MAX V CPLD.
