port is asserted high, the function is asynchronously cleared.

clock Yes Clock input to the ALTMULT_COMPLEX function.

dataa_imag[] Yes Imaginary input value for the data A port of the complex

multiplier. The size of the input port depends on the WIDTH_A

parameter value.

dataa_real[] Yes Real input value for the data A port of the complex multiplier.

The size of the input port depends on the WIDTH_A parameter

value.

datab_imag[] Yes Imaginary input value for the data B port of the complex

multiplier. The size of the input port depends on the WIDTH_B

parameter value.

datab_real[] Yes Real input value for the data B port of the complex multiplier.

The size of the input port depends on the WIDTH_B parameter

value.

ena No Active high clock enable for the clock port of the complex

multiplier.

Table 10-3: ALTMULT_COMPLEX IP Core Output Ports

Port Name Required Description

result_imag Yes Imaginary output value of the multiplier. The size of the output

port depends on the WIDTH_RESULT parameter value.
