10.1 iMPACT - Spartan-3A/AN/DSP - DNA readback format

Description

The option was added in iMPACT 10.1.03 to readback the device DNA value for the Spartan-3A/AN/DSP, but how is the data shifted out?

Solution

The format is the same as seen in UG332. The LSB is on the left hand side and the MSB is on the right hand side. The DNA reference design displays the DNA with the MSB on the left hand side and the LSB on the right hand side, which is opposite of what impact displays.
