[SOLVED] Error vsim-8630: Infinity result from division operation

[nervecell_23]

When I ran a testbench in modelsim I've got vsim-8630 error referring to a line: result = A/B + C/D;
A,B,C and D are 'real', A = 17396, B = 186, C/D=1, therefore the result does have an infinite result.
Although in modelsim this error was reported, correct result was shown in waveform with the value being rounded to four decimal number (94.5269) and the insertion of error did not interrupt the simulation.

Is it safe to ignore this error? If not, where should I start to resolve this error?
Thanks

Post the code so we don't have to guess...but my guess is that either B or D is a signal and that the error is reported at t=0. One simulation delta later B or D then went to the appropriate value and therefore so did the computation. Drag A, B, C, D and result to the Modelsim list window to investigate it further for yourself to see what the cause of the error might be.
