Hi,
I am reading data from a file which contains the pixel values of column of image. I am performing the transient analysis using spectre to get the output (out here) at each time event. I have tried, just to check, different length of simulations but the response is same as shown in the attached figure. Also, simulation does not stop and continue to stop. Please help.
// VerilogA for Verilog_A, data_readout, veriloga
`include "constants.vams"
`include "disciplines.vams"
module module_filereader (out);
output out;
electrical out;
parameter real period = 1/10k;
parameter integer maxcount = 480;
integer dataread, cnt;
real mydata1, mydata2;
real datacol [maxcount-1:0];
analog begin
@(initial_step("tran")) begin
cnt = 0;
dataread = $fopen("/mnt/cnm/khan/Amir_IC/Building_block/One_column_image1.csv","r"); //opening file readable access
end
@(timer(0, period )) begin
cnt = cnt+1;
end
while( cnt < maxcount ) begin
mydata1 = $fscanf(dataread,"%f", datacol[cnt]);
// mydata1 = $fscanf(dataread,"%f",cnt);
end
$debug("\nThe value of variable mydata1 is %f",mydata1);
@(final_step) $fclose(dataread);
V(out) <+ transition(mydata1, 1n, 1n, 1n);
end
endmodule
