- Introduction :
-
- "JEDMAN" is a utility package that would allow its users
- to manipulate JEDEC data files. Its basic features are
- checksum recalculation and translation of 22V10 to 32VX10 MMI PAL
- JEDEC files. These features are described in the following
- sections. It is assumed that all JEDEC files, to be successfully
- processed by "JEDMAN", must conform to JEDEC Standard No. 3-A
- (May, 1986) . One further assumption made is that the Jedec
- default fuse setting is set F0. All fuses in the JEDEC file are
- set to 0 by default.
-
-
- 1) Checksum Recalculation :
-
- This option in "JEDMAN" is useful when modifications are
- made to the JEDEC file. Making such modifications may be
- necessary when attempting to download JEDEC data to a programmer.
- The modified file is processed by "JEDMAN" and the recalculated
- checksums are appended. In addition, this option will renumber
- test vectors in case any test vectors have been added or deleted.
- Furthermore, fuse data in the JEDEC file may be overridden by re-
- specifying the fuse states for correctly numbered fuses. This
- program will not detect any errors in JEDEC files, and hence,
- such modifications must be made with care. The fuse and transmit
- checksums are appended appropriately, and an output JEDEC file is
- created.
-
- 2) Translation to MMI parts :
-
- There are many obvious advantages to converting designs that
- use non-MMI parts to equivalent designs that use MMI devices.
- With this option, any 22V10 JEDEC file is converted to a 32VX10
- JEDEC file that implements the same design (at the functional
- level).
