Early Power estimator Problem (Please help)

Hello, 

Steps taken, 

 

I generated my VCD file modelsim 

I even converted it to wlf to make sure it was right 

 

 

Output from estimator: 

I/O Thermal power dissipation 2605mW 

Core Dynamic power 446mW 

Static Power 112.38mW 

 

 

module topmodule1(CLK,RST,en,Xin,en_ram1,ram1_we_addr,en_ram2,ram2_we_addr, out_ram2,in_ram2,rd_ram2,Yout); 

 

input CLK; 

input RST; 

input en; 

input [31:0] in_ram2; 

input [31:0] Xin; 

output reg [5:0] ram1_we_addr,ram2_we_addr;  

output reg en_ram1, en_ram2,rd_ram2; 

output reg [31:0] out_ram2; 

output reg [31:0] Yout; 

 

The addresses go to an external memory, and the "out_ram" are the datas from the external memory. 

 

 

Attached are the pictures from the power analyzer 

The power dissipated by the multpliers are 0. I am so confused because they synthesized (when I look at the number of multpliers).

Could it be that my VCD file is wrong? 

 

 

I used the toggle rate 12.5% with no VCD file (toggle_rate.jpg) 

 

 

then i set the toggle rate to 50% with no VCD filter (toggle_rate_50.jpg) and the values make better sense
