Description
By default, MAX® 7000S, 7000AE, 7000B, and 3000A devices power-up with registers cleared or reset. For MAX 7000AE and 7000B devices, a logic option allows individual registers to be set to power-up high if desired. MAX 3000A devices do not have this option and therefore always power-up cleared.
For more information on the power up level logic option, refer to Quartus II Handbook, Volume 1, Section II Chapter 6: Recommended HDL Coding Styles (PDF).
