I/O Pin State File Definition (.ips)

An ASCII text file (with the extension .ips) containing pin state information for specific devices used to configure pin states during programming.

You can create IPS Files by pointing to Create/Update and then clicking IPS File on the File menu.

You can also assign pin states to pins using logic options in the Assignment Editor. Pin state assignments made in the Assignment Editor are stored in the Intel® Quartus® Prime Settings File (.qsf) or Programmer Object File (.pof) and are overridden during programming by any changes defined in an IPS File.
