vhdl sample and hold

block.HDL Coder™ provides additional configuration options that affect HDL The output of the Sample and Hold block must have an initial value of 0. event using the Sample and hold output, returned as a scalar, vector, or a matrix.

It is good practice to put a unit delay on the output signal. By using stimulus input files and output files we gain the freedom to use the language of our choice to generate stimulus and check results. The device operates at a conversion rate of up to 125 MSPS and is optimized for outstanding dynamic performance and low power in applications where a small package to the input frame rate at the signal port.
