The number of FIR taps is an indication of the amount of memory required to implement the filter.4Introduction•One of the most fundamental elements for a DSP system is an FIR Filter. •There is no feedback, which results in a finite output value of zero.•The filter is mathematically expressed using the following difference equation:Piiinxbny0)()(5FIR Block Diagram•The FIR Filter consist of three main components:1) A D Flip-Flop to implement a simple delay.2) A Multiplier to implement the coefficients, which in our case we are using a Boxcar filter, meaning all coefficients are 1.3) A Full adder to sum the nodes at the end of each Tap.6Longest Path CalculationsPHL5ns18.28ns7Schematic8Layout9Successful DRC check10Successful Extraction Report11Successful LVS Report12Successful LVS Report cont.13Simulations14Simulations15Simulation16Simulation17Post Extraction18Post Extraction cont.19Propagation Delay Waveform20Propagation Delay21Cost Analysis•Estimated time spent on each phase of the project:–Verifying Logic = 2 weeks–Verifying Timing = N/A–Layout = 15 hours –Post Extracted Timing = 5 hours22Lessons Learned•A project of this nature requires ample time to complete it, before its deadline.•Verify logic of individual components.•Extra care needed when designing the layout.23Summary•Because FIR Filters are such an important element of DSP design, it was beneficial to do a project like this to strengthen understanding of the concept•A low cost, easy to implement Boxcar FIR filter was designed and tested•Due to the nature of DSP, FIR filters of some form will always be needed.24Acknowledgements•Dr. Parent, for teaching us not to overcomplicate our
