Port maps in vhdl
WebOct 15, 2013 · Re: Can i do conditional port mapping in VHDL?? you cannot do conditional port maping, a port mapping is like the pins on a chip. So disconnecting them would be impossible while the design is running. How about posting some trial code, and we'll try and fix it.

When we write VHDL code, we may also wish to leave some ports unconnected. For example, we may have a component which models the behaviour of a JK flip flop.
