Project Update

It has been a few weeks since I made a record of my progress. Since the last update I have completed the RTL for the "interpolation filter" block and started developing the verification environment.

A high level overview / update

• Complete:
• RTL for the sub-blocks
• Zero Stuffing
• Filtering
• Decimation
• Rounding/Scaling
• Integrated the sub-blocks into a top level "interpolation filter" block
• In progress:
• Verification Environment:
• Leveraging common code from the "ADC to samples" block
• Generalizing interfaces and low level verification components for different sample bit-widths
• Conceptualizing a few useful test cases.
• Selecting filter coefficients that do interpolation and low pass filtering. I'm planing to use MATLAB to help on this one.
• Need to clean up the documentation of the top level block and the low level sub-blocks

This block is a bit boring so far. Writing the RTL and starting the verification environment has been a bit of a grind. I'm still very excited about the scoreboard aspect of this block. The scoreboard will require me to learn DPI and do some fixed point math fun in C.
