RTL module compile error #67

Closed aazz44ss closed 6 years ago

aazz44ss commented 6 years ago

Is mult_add_fix8bx4 module takes 8 char type input and get an int type output? and is there any restriction to use this RTL module? like it only fit on PipeCNN? I have compiled PipeCNN correctly. and I try to use mult_add_fix8bx4 module is my code, the result in emulator is correct, however the compiler failed to compiled it.
