ID:335091 TimeQuest Timing Analyzer found <number of latches> latches that cannot be analyzed as synchronous elements.

CAUSE: The TimeQuest Timing Analyzer found latches across multiple look-up tables (LUTs). The TimeQuest analyzer does not support analyzing this latch implementation as a synchronous element, but treats these latches as a combinational loop.

ACTION: You must implement these latches with registers using asynchronous load and data signals, or remove these latches from your design. For more information, run the check_timing tcl command in the TimeQuest analyzer.
