[SOLVED] What is the meaning of "not synthesizable" in verilog?

WebWrite synthesizable and automatic tasks in Verilog. Tasks are sections of Verilog code that allow the Digital Designer to write more reusable, easier to read code. Tasks are very handy in testbench simulations because tasks can include timing delays. This is one of the main differences between tasks and functions, functions do not allow time ...

"WebThis is not synthesizable; it is not modeling real hardware. If you need to set some state to an initial condition, you must explicitly use the reset signal. 19 Triggering a sequential block off of the negedge of a signal is certainly synthesizable, but we will be exclu-sively using a positive-edge-triggered ﬂip-ﬂop-based design style.
