Hprep6 Options

–n (Specify Signature Value for Readback)

-n [signature]

The –signature option is applicable to the XC9500/XL/XV devices only. The value entered in the signature field programs a set of bits in the CPLD that may be read-back via JTAG after programming. This is often used as to identify the version of a design programmed into a device.

Note: The CoolRunner family also allows for a signature value, but it must be entered by the programming tool (for instance, IMPACT or third party programmer).

–nopullup (Disable Pullups)

The -nopullup option instructs Hprep6 to disable the pullups on empty function blocks. By default, pullups are enabled to minimize leakage current and prevent floating I/Os.

Note: The –nopullup option applies to XC9500/XL/XV devices only.

–s (Produce ISC File)

The –s option instructs Hprep6 to output an additional programming file in ISC IEEE1532 format.

Note: ISC IEEE532 output is not available for the CoolRunner XPLA3 family.

–tmv (Specify Test Vector File)

-tmvfilename

The -tmv option is used to specify a test vector file for use with iMPACT’s functional test operation. The output .tmv file is in ABEL format.
