*Obsolete* 4.2i PROM File Formatter - Does the PROM File Formatter check for the correct start-up clock?

Description

Keywords: CCLK, JTAG, startup, start-up, check, PROM File Formatter, correct clock

Urgency: Standard

General Description:
Does the PROM File Formatter check for the correct start-up clock when an MCS file is created? Is it possible to generate an MCS file that has the startup clock set to a JTAG clock?

Solution

In the current software (ISE 4.2i), the PROM File Formatter does NOT check to ensure that the startup clock is set to CCLK. If the startup clock is set to JTAG, the configuration from the PROM will fail, and the DONE pin will not go High.

However, the File Generation portion of the iMPACT tool does check for the correct startup clock.
