Sorry for the inconvenience. And thank you for explaining regarding push function as I couldn't really understand regarding pushing a hash reference onto @array. The input data is actually named as test.v. Below here is the text file. 
module circuit_17 (n1,n2,n3,n6,n7,n22,n23);
input n1,n2,n3,n6,n7;
output n22,n23;
wire n10,n11,n16,n19;
nand nand2_1 (n10,n1,n3);
nand nand2_2 (n11,n3,n6);
nand nand2_3 (n16,n11,n2);
nand nand2_4 (n19,n11,n7);
nand nand2_5 (n22,n10,n16);
nand nand2_6 (n23,n16,n19);
endmodule
