Spacing for IO pins

tswong

Does anyone know how to set the absolute spacing of I/O pins when doing the I/O place inside the PREVIEW?  Can I set the value on I/O constraint file?

    Tswong,

    Could you please tell me exactly what you try to achieve ?

    Because it seems you have already pre-constrained pins fom top level or from an other block and you would like to mimic the placement in this block.If it is teh case then I can propose some other way to do it.

     For the 're-space' you can find the command in 'Edit -> Soft Pins -> Respace'. 

    You have the deatils on the command at:

    You need to search for 'Respacing Soft Pins'

    Thanks,

    Alex
