Inferring / instantiating dual-port read-only memory, with:

* dual clock, clock enable,
* 2 read ports.

The generalized behavior across Altera and Xilinx FPGAs since
Stratix/Cyclone and Spartan-3/Virtex-5, respectively, is as follows:

WARNING: The simulated behavior on RT-level is not correct.

TODO: add timing diagram
TODO: implement correct behavior for RT-level simulation
