Due to a problem in the Quartus® Prime Standard Edition version 16.1 and earlier, you may see this error when simulating the ALTFP_LOG IP.
To work around this problem, comment out the sclr port in the file, <ALTFP_LOG IP name>.v:
altsquare squarer
(
.aclr(aclr),
.clock(clock),
.data(squarerIn),
.ena(clk_en),
.result(wire_squarer_result)
`ifndef FORMAL_VERIFICATION
// synopsys translate_off
`endif
//,
//.sclr(1'b0)
`ifndef FORMAL_VERIFICATION
// synopsys translate_on
`endif
);
This problem is scheduled to be fixed in a future release of the Quartus Prime Standard Edition software.
