 +====== Nested namespaces ======
 +
 +The ''std'' namespace contains a number of nested namespaces:
 +
 +  * [[data|data]]: Standard data types
 +  * [[channels|channels]]: Standard channel definitions
 +  * [[gates|gates]]: Commonly used gates
 +  * [[cells|cells]]: A simple synchronous standard-cell library
 +  * [[io|io]]: Standard I/O primitives
