- Design Validation Review (required)
A complete and comprehensive design validation review is required
for all design submissions and is prompted for by AMCCSUBMIT.
In cases where there is no software support for design rules, the
designer must perform the validation checks manually and submit the
- I/O List (required)
The list of all signal I/O, added power and ground pads and fixed
power and ground pads including signal I/O type (TTL standard, TTL
open-collector, TTL 3-state, ECL 10K, ECL 100K, etc.) and clear identification
of simultaneously switching outputs is generated by AMCCERC and called
AMCCIO.LST. It must be included in the hardcopy and media documentation.
- Annotation Level
Space is provided on the submission checklist for annotation level,
either Front-Annotation or Back-Annotation. Back-Annotation submissions
are currently handled as special cases.
- Maximum Operating Frequency
The specified maximum operating frequency is the frequency at which
the At-Speed simulation must be run; specify it in MHz or GHz.
The total power in Watts is to be computed or estimated. This includes
DC power and any AC power, following the directions in Volume I, Section
5 of the design manual specific to the AMCC array series.
Specify any differences between the total power entered here and
the power computed by AMCCERC. The difference may be the AC power
computation, different termination loading or duty cycles.
- Annotation and Output Loading (required)
AMCCANN allows the package type, package pin capacitance and system
loading to be specified for the circuit. Commentary information on
frequency must be added for high-speed I/O (see Section 4). The list
of all signals with pad placement (if known), package pin capacitance
(Front-Annotation or Back-Annotation), and system load is called AMCCPKG.LST.
It must be included in the hardcopy and media documentation.
The output.dly data file generated by AMCCANN must be included
The output capacitive load delays are included in the annotation
files and is reflected in the simulation results. The delay files
used in the simulations must be submitted on media. For Front-Annotation
these are: FNTxxx[x].yyy, where xxx[x] is the simulation type (mil,
com, min, nom,c5mx, c5mn, etc.) and yyy is the extension denoting
the system used (dsy, val, men, ver, lsr, etc.). Back-Annotation uses
BCKxxx[x].yyy. Refer to Volume I, Section 3 for a detailed list of
the files used with a particular array series.
- Cross Reference (optional)
The AMCC cross-reference file, AMCCXREF.LST can be submitted on media.
It is currently not required.
- Function Description of the Circuit (optional)
AMCC prefers that a high-level functional description of the circuit
on the array be included in the hardcopy documentation. This description
should include the required performance of the circuit, any timing
constraints, interface requirements, testing specifications and the
- Block Diagram of the Circuit ..(optional)
Unless a hierarchical schematic capture has been performed, AMCC
prefers that a top-level block diagram of the circuit as configured
for the array be included in the hardcopy documentation. If a hierarchical
schematic capture has been performed, the top-level schematic may
- Preplacement Requests (optional)
Preplacement of macros for critical timing requirements can be submitted
to AMCC if the designer feels it to be necessary. All preplacement
requests will be evaluated by AMCC, and the designer will be notified
if they can or cannot be met.
- Pin-Out Requests (optional)
I/O placement may be of concern in a design, and the designer may
wish to specify a pin-out request to AMCC. The final pin-out is driven
by layout considerations and restrictions. The pin-out requests will
be evaluated by AMCC, and the designer will be notified if they can
or cannot be met.
- Critical Path and Timing Requirements (required)
The maximum required frequency of operation for the circuit and the
expected performance for the critical paths should be clearly stated
in the hardcopy documentation following the procedure discussed in
"Vector Submission Rules and Guidelines" in the AMCC design
manual. Use the Timing Correlation report form for any path not covered
by an AC Test.
- Waivers - Approved PARS
Attach any preapproval requests that have been approved to the design
submission package and list them by number on page 6-A-2. These include
custom macros, design rule variations, approved AMCCERC errors, approved
timing check errors, and approved AMCCVRC errors.
