`include "disciplines.vams"
`include "constants.vams"
 
module fileexample;
 
integer mcd1 ;
integer mcd2 ;
 
integer mcd ;
analog begin 
@(initial_step) begin
mcd1 = $fopen("file11.txt","a") ;
mcd2 = $fopen("file2.txt","a") ;
end
 
mcd = mcd1 | mcd2 ; 
$fstrobe(mcd, "This is written to both files") ;
 
 
 
   $fclose(mcd1); 
   $fclose(mcd2);
 
end
endmodule

However, i am getting as error ---->

cyclically dependent cells found: FileTest(I0) - FileTest(I0)
1 error(s), 0 warning(s)

I would be grateful if someone told me how to solve this problem
thank you in advance
 

Code: 
@(final_step) begin
   $fclose(mcd1); 
   $fclose(mcd2);
end //final_step

Show me netlist which call this verilog-A module.
 

Code: 
simulator lang=local


parameters 

I0 out x0 x1 nand2 

subckt nand2 out in1 in2 
V6 n3_1 gnd vsource type=dc dc=1.3 
M7 out in1 n4_4 gnd n w=0.0001 l=1.3e-007 
M9 out in2 n3_1 n3_1 p w=0.0001 l=1.3e-007 
M10 out in1 n3_1 n3_1 p w=0.0001 l=1.3e-007 
M8 n4_4 in2 gnd gnd n w=0.0001 l=1.3e-007 
ends


TimeSweep tran start=0.000000e+000 stop=5.000000e-003 lteratio=3.500000e+000
