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

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 code

Dear all
I need to instantiate an Altera float-point matrix **multiplier** megafunction in my design, and plan to implement it with a one-hot state machine.
The problem is that the filed generated by the quartus megafunction wizard have errors, such as in the .v (I use **verilog**) file there is Error (272006): MGL_INTERNAL_ERROR: Port altfp_matrix_mult|

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

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

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

Hey all,
I was wondering if you could help me with my homework.
I need to implement a 4-bit **multiplier** at the gate-level in **verilog** using AND gates and adders
I've drawn the layout, but I'm having trouble translating it to **verilog**.
When I instantiate an AND-gate, how do I extract the least significant bit from the AND's output? (...)

Hi,
I'm trying to code a signed **multiplier**, and I used 'signed' for the ports and wire, but when I run (ModelSim) simulation to check it, it doesn't work for me.
Below is the code and the simple testbench. The numbers are the most positive (0xFF) * most negative (0x2000). In simulation, I get 0x1FE000, which is not the correct answer. Any idea

I am designing (256x256)-bit **multiplier** using DSP blocks available on Xilinx FPGAs. I split operands into several chunks of 64-bits, using Karatsuba technique 256-bit **multiplier** can be constructed using 3, 128-bit **multiplier**s each of which are further realized by 3, 64-bit **multiplier**s. i have constructed 64-bit (...)

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
