Design Submission
Last Edit September 2, 2001
At-Speed Simulation Submission (Required)
The submitted at-speed simulation is rerun after layout to verify the
actual timing performance for the array. The Back-Annotation delay file,
which provides the actual metal delays for the layout, is used in place
of the Front-Annotation delay file. The circuit.pkg file provides package
pin capacitance based on final placement to replace the estimates for
package pin capacitance in the output.dly file.
At-speed simulation results provide an evaluation of the timing performance
and help identify timing violations and potential timing problems. The
customer must supply all at-speed simulation vectors.
AMCC requires that at-speed simulations be performed at the specified
maximum operating frequency, and be performed using the minimum library
and then again using the maximum worst-case library. Refer to Volume I,
Section 3 for the specific series to determine which library is maximum
and which minimum for the array.
The at-speed simulation, if required, should be performed following the
procedures described in the design manual.
At-Speed Simulation Documentation
The documentation required for at-speed simulation submission is prompted
for by the AMCCSUBMIT program interface. Before running AMCCSUBMIT, simulation
files for the paths, both in sampled and in print-on-change format should
exist. All AMCCSUBMIT errors should be resolved prior to submission.
Documentation included on disk or tape for the sampled at-speed simulation
file includes:
- the file number (1..n); no paging of at-speed files is required or
necessary;
- the sampled AMCCSIMFMT file
- whether this was a MIN or MAX simulation; PRODUCT_GRADE is prompted
on the form header (identifies the annotation file);
- the simulation control file name;
- the simulation input file name, if any;
- the simulation command file name which may be submit procedures, a
transcript of system operation during simulation, including VIEW, RUN,
START, LIST, WRITE, etc. statements as required for the specific system;
- the name of the text file version of the data or the control file
which clearly describes the testing performed;
- the timing check report for the file (all simulations done for submission
use timing checks active).
Documentation included on disk or tape for the print on change at-speed
simulation file includes:
- everything included to document the sampled at-speed simulation except
that the sampled AMCCSIMFMT file is replaced by the print on change
AMCCSIMFMT file.
