Things to note: there's a good variety of basic gates, including quite a few multi-level gates, such as AND-OR gate. There's also I/O pads, flip-flops and special function cells. Many gates are available with various output powers.

For each gate there are comprehensive figures that enable one to predict its delay, taking into account its track loading, how many other gates it is feeding and the current supply voltage.
