Sectioning in DE HDL

admin

Hi, a newbie 's question. What does sectioning do in DE HDL?

So far I only learnt that sectioning a part can display the pin numbers of all the pins of that particular part, and of course a psm must be mapped to that part symbol initially.

Thanks in advance.

    You're correct, the DEHDL Section command will add the part's pin numbers to its pin stubs. However, the preferred method of seeing the pin numbers is to run Export Physical and insure the back annotation option is enabled. This will add pin numbers to all the parts in the entire design.

     Using the Section command, while it does display pin numbers, will "fix" those pin numbers so that the PCB designer will not be able to swap gates within a footprint. Essentially, you're conveying that you don't want those pins to be swapped. This is why you should only use the Section command if you want to prevent pin swapping. The PCB designer does have an override capability, but it's not often used.

    Does anyone know there is a way to 'SECTION' all parts in a design? Even I did "Export Physical ", some parts are still not showing any section pin numbers. What could be issues causing this? library? How to fix it?
