- SLR: Super Logic Region number for SSI (Stacked Silicon Interconnect) devices.
- ByteGrp: memory byte group number. e.g. for DDR3 interface, DQS and associated DQ pins need to be placed in the same byte group.
- Min/Max Dly ps: minimum/maximum flight time in pico second. These numbers directly come from the device package file and correlate well with calculations using IBIS models.

Spartan6 Pin Table View Enhancements in v0.44.2
ADEPT v0.44.2 includes several enhancements to the Spartan6 Pin Table View:
- The flight time for Spartan6 devices can be also calculated from data in IBIS models. Follow the instructions on the blog: Calculate IO flight time using IBIS model (Of course, download Spartan6 IBIS models instead)
- Two new columns, IN_TERM and OUT_TERM, are added to display the IN_TERM and OUT_TERM constraints for Spartan6 IOs. Together with the "DIFF_TERM" column, the S6 pin table view now covers all IO termination configurations. These three columns can be populated by
- constraints in a UCF (File->Read UCF menu) or
- configurations in a NCD file (Read NCD with "Get Pin assignments/attributes" checked)
