15 years ago"not steady enough" is far from specifying a clear problem I fear.
Generally, didvided clocks can be used as peripheral clock. There may be problems: - to achieve a specific timing relation between the divided clock and the system clock when processing the pheripheral input or generating the output signals - the clock output can have glitches, if it's erroneously sourced by cominational logic rather than a register - jitter of the FPGA clock tree can be an issue in acquisition of high speed signals Apart from the latter, the problems can be overcome. The best way to generate a peripheral clock with specified timing is using a PLL clock divider.
