8 Bit Serial Adder Vhdl Code For 8 !!EXCLUSIVE!!


I am writing a VHDL code to impelemt 8 bit serial adder with accumulator.When i do simulation, the output is always zeros! And some times it gives me the same number but with a shift ! I dont know what is the problem, i tried to put A,B as inout but didnt work as well. Can anybody help please.




8 Bit Serial Adder Vhdl Code For 8

So I have to make a 8 bit carry select adder for my lab. I looked on wikipedia where I found a diagram for a carry-select adder of n-bits and created what I think should be correct but when I run the simulation I get an incorrect answer. I am attaching my vhdl code if anyone can tell me what is wrong to correctly model a 8 bit carry select adder I would appreciate it.


To generate HDL Code with DA architecture, invoke the generatehdl command, passing in a valid value to the 'DALUTPartition' property. The 'DALUTPartition' property directs the code generator to use DA architecture, and divides the LUT into a specified number of partitions. The 'DALUTPartition' property specifies the number of LUT partitions, and the number of the taps associated with each partition. For a filter with many taps it is best to divide the taps into a number of LUTs, with each LUT storing the sum of coefficients for only the taps associated with it. The sum of the LUT outputs is computed in a tree structure of adders.


When you specify this option, HDL Coder chooses between the CSD or FCSD optimizations. The coder chooses the optimization that yields the most area-efficient implementation, based on the number of adders required. When you specify 'auto', the coder does not use multipliers, unless conditions are such that CSD or FCSD optimizations are not possible (for example, if the design uses floating-point arithmetic).


The block provides three filter structures. The direct form systolic architecture provides a fully parallel implementation that makes efficient use of Intel and Xilinx DSP blocks. The direct form transposed architecture is a fully parallel implementation and is suitable for FPGA and ASIC applications. The partly serial systolic architecture provides a configurable serial implementation that makes efficient use of FPGA DSP blocks. For a filter implementation that matches multipliers, pipeline registers, and pre-adders to the DSP configuration of your FPGA vendor, specify your target device when you generate HDL code.


This table shows post-synthesis resource utilization for the HDL code generated from the Partly Serial Systolic FIR Filter Implementation example. The implementation is for a 32-tap FIR filter with 16-bit scalar input, 16-bit coefficients, and a serialization factor of 8 cycles between valid input samples. The synthesis targets a Xilinx Virtex-6 (XC6VLX240T-1FF1156) FPGA. The Global HDL reset type parameter is Synchronous and Minimize clock enables is selected.


This table shows post-synthesis resource utilization for the HDL code generated from the 32-tap filter in the Partly Serial Systolic FIR Filter Implementation example, with the Number of cycles parameter set to Inf. This configuration implements a fully-serial filter. The synthesis targets a Xilinx Virtex-6 (XC6VLX240T-1FF1156) FPGA. The Global HDL reset type parameter is Synchronous and Minimize clock enables is selected.
