What can I do for 'Main Optimizer failed' error in Intel HLS?

Dear Mr. Anand

I am sorry. I can't share any files because of our company policy.

But I add pseudo code. build.bat is changed only cpp filename and -ghdl option for test-fpga.

# include <>

...

typedef ac_fixed<8,8,false> fixed8;

typedef ac_fixed<1,1,false> fixed1;

typedef ac_fixed<10,10,false> fixed10;

component void func(stream_in<fixed8> a, stream_in<fixed1> b, stream_out<fixed10> c) {

hls_init_on_reset static fixed8 d[xx];

hls_init_on_reset static fixed1 e[xx];

for (){

// Non blocking read1

bool success = false;

fixed8 data = a.tryRead(success);

if (success) {

//Shift register

# pragma unroll

for ...

d[] = data;

}

// Non blocking read2

bool success1 = false;

fixed8 data1 = b.tryRead(success1);

if (success1) {

//Shift register

# pragma unroll

for ...

e[] = data1;

}

//--------------- The following makes error ----------------

fixed10 m = d[] *e[];

...

c.write(out);

}

}

int main() {

//Generate stream in data and buffer

// Invoke component

return 0;

}

That's all. What can I do?
