Specify testing options for coefficient memory interface for FIR or IIR filters
 : Empty vector (default)
When the value of
unspecified (or set to the default value of
the test bench loads the coefficients from the filter object and then
forces the input stimuli. This shows the response to the input stimuli
and verifies that the interface writes one set of coefficients into
the RAM as expected.
(For FIR filters): vector of coefficient values . In this case,
the filter processes the input stimuli twice. First, the test bench
loads the coefficients from the filter object and forces the input
stimuli to show the response. Then, the filter loads the set of coefficients
specified in the
and shows the response by processing the same input stimuli for a
second time. In this case, the internal states of the filter, as set
by the first run of the input stimulus, are retained. The test bench
verifies that the interface writes two different sets of coefficients
into the RAM. See Programmable Filter Coefficients
for FIR Filters for further information.
(for IIR filters): Cell array containing a column vector of scale values, and a second-order section (SOS) matrix for the filter. See Programmable Filter Coefficients for IIR Filters for further information.
