    Design Entry HDL grid errors Reply

     I have been trying to build a schematic and the grids are not loading properly.

     Under Tool, Options, Grids, I have set my grid to Decimal, Show Logic Grid - On, Size 0.025, Multiple 1.

    But the console show my grid as size 0.024  1.

    When I check the grid size I have dots at 0.012 pitch.???????

    Can anyone enlighten as to why the grids are nothing like those required. And the components will not lock on the correct grid to make a clean schematic.

    The impossible we do straight away. Miracles take a little longer.

    DEHDL does not allow odd number values for the grid setting. That’s why you’re seeing the “rounding” to

    an even value grid display.

     I have been told the grid has a default setting of 500. This gives a grid of 1/500 or 0.002".

    There is a setting you can place in an environment variable to change the default to 1000. Giving a grid of 1/1000 or 0.001".

    I would be VERY cautious I changing the grid to this small of a resolution. Attempting to connect pin stubs to wires, place properties, etc. will be difficult after you change the value back to grid 0.1 5 (the default). The small resolution you mention below should only be used in rare circumstances and primarily by librarians who are adjusting graphics within a symbol view. It should be avoided by designers entering schematic data.
