sv中$bitstorealshort() 函数

在sv中用$bitstorealshort()函数可以轻松的将十六进制，二进制数转化成单精度浮点数，以下为源代码，在modelsim10.1c中测试通过，文件需要保存为.sv文件

module h2f;

integer fid_rd;

integer fid_wr;

// integer fid_mif;

bit [11:0] variable=0;

bit [31:0] value;

int  h_array[0:1023];

shortreal fr;

initial begin:file_rd

fid_rd = $fopen("rd_h.txt","r");

if(fid_rd == 0)

disable file_rd;

while(!$feof(fid_rd))begin

if(!$feof(fid_rd)== -1)

break;

$fscanf(fid_rd,"%h",value);

h_array[variable] = value;

variable = variable + 1‘b1;

end

$fclose(fid_rd);

fid_wr = $fopen("h2f.txt","w");

foreach(h_array[i])begin

fr = $bitstoshortreal(h_array[i]);

$display("%d %f",i,fr);

$fdisplay(fid_wr,"%f",fr);

end

$fclose(fid_wr);

end
