This directory contains the files describing the HLS benchmark
example, the elliptic wave filter. They are organized as follows :
o ellip.vhdl : The VHDL behavioral model for the elliptical
filter.
o ellip.doc : Describes the elliptic filter in brief.
o test_vectors.vhdl : A 'test' process built around the VHDL
model of the elliptical filter.
o test_vectors.doc : A brief document on the test vectors
described in "test_vectors.vhdl".
o cmd.inc : Simulation command file for running the test vectors
on the Zycad simulator.
*****************************************************************
To run the test vectors for elliptic filter
*****************************************************************
(a) Compile the three VHDL files -- bit_functions.vhdl, ellip.vhdl
and test_vectors.vhdl -- by invoking the command
zvan <vhdl file name with extension>
(b) Run the simulation using the command
zvsim -t ns -i cmd.inc E
The simulation output will appear in a file called "run.out".
If there are any errors in simulation, "Assert" statements
will appear in this file, mentioning the port at which the
error occurred and the expected value.
