## multiplier 8*8 bit in verilog

just out of curiosity, how do you guys do math in FPGA? Take multiplication for example, I always invoke IPcore, except when come coefficients are constants then I'd use shift and add. As to other operations such as cordic...IPcore is my first choice... Multiplication I almost always do as a * b. It makes for

## Primetime Voltage scaling

Hi, I am using Primetime to perform Voltage scaling, then i need to get timing and power change. When I use set_voltage, i can see changes in power, timing remains the same. I have a combinational multiplier design. No clocks in verilog code. I am trying to use set_rail_voltage, but i dont know clear way. I am trying to use the following (...)

## Improving Power Consumption

I came across a verilog example of improving power consumption in a multiplier. The original code is reg Enable; reg A, B, DataOut, MultOut, AddOut; wire A, B; always@(posedge clock) if (Enable == 1) DataOut <= MultOut; else DataOut <= AddOut; assign MultOut = A * B; assign AddOut = A + B; The assumption

## Can we make this huge verilog code(32 bit multiplier) into small one?

As vGootimes said the FPGA equivalent to the huge, un-maintainable mess of structural verilog, would be this: module multiplier ( input a, input b, output p ); assign p = a * b; endmodule But if you want high performance you'll probably want to add a clock and include some pipeline registe

## How to write verilog code for fft using vedic multiplier in spartan3 family?

## [moved] Need VHDL code for floating point multiplier

Unfortunate the floating point vendor libraries aren't provided as VHDL sources, most likely they even haven't been written in VHDL or verilog. They are designed to use the DSP hardware of different FPGA families in an optimal way, using respective low-level primitives. Altera e.g. is typically writing this stuff in AHDL. For the same reason, wr

## How to instantiate two different modules based on a condition in verilog?

Are you asking about a parameterizable module, where the bit length of some inputs is defined by a parameter, or do you mean that the length is variable at runtime? A generate construct can only work for the first case. generate if (SIZEPAR == 8) // instantiate 8x8 multiplier else // instantiate 4x4 mutiplier endgenerate

## 8*8 verilog multiplier

The code doesn't describe synthesizable hardware. It looks like you don't understand what a HDL for loop means. It's a method to replicate hardware elements, not performing a sequence in time. The code can probably run in simulation if z_temp is cleared before the loop. Adding the multiplicator n times is also the worst way to make a multipli

## verilog code for generic multiplier using repeat

Can any body help me in doing verilog code for generic multiplier ?

Hi, my code currently looks like this. Is there any way my code can accept non integer numbers (A=3.05). I read that my output has to be a reg type so how can we represent multiplication, division or addition using non integers? For ex. 3.05 + 1.07 or 1.06*5.01. If the output must be of type reg. I read online that there are very complicate

## verilog code for a frequency multiplier

i really need to know if is possible to multiply a clock frequency in verilog or maybe someone can explain me how to delay a clock signal with a quarter of a period

## 32x32 multiplier:is a a shorter code possible in verilog ?

To my understanding: 1): If you want to synthesis that multiplier, you just write mul = a * b; will be ok. Then synthesis tool will synthesis this code to logic gates. 2): If you want to design a multiplier (design a multiplier architecture) with simple logic functions, such as add, OR, AND, you may need rearch the (...)

## clock multiplier in verilog with model sim

## Designing a 2's Complement Multiplier

With twos compliment, there is no need to worry about whether values are positive or negative. All you need to do is sign extend both inputs. You either need to instantiate an onboard multiplier or N adders, where N is the number of bits at input. lets take an example, -3 x 5 (1101 x 0101) 1 1 0 1 x 0 1 0 1
