Output pin naming rules in sub-modules.

[NShan12]

Hello,

I have a FPGA project designed completely as schematic entry. There is a module instantiated at top level and the output of this module is a 12 bit vector with name "2pi". Compilation is through and quartus doesnt throw any error even though the variable name "2pi" starts with a digit.

Is it okay to continue like this? is it alright to have variable names starting with a digit in schematic entry?

Hi Naveen,

Even though the schematic can run through the compilation, it is not recommended to naming the variable starting with number. Try to declare the variable starting with alphabet and the follow up by number.

Thanks,

Regards

Hello @SyafieqS ,

Thank you. I will rename the variable names as suggested.
