+Given the current ''W''-bit state of a Fibonacci-style linear feedback shift register (LFSR), compute the next state. The LFSR has ''N'' taps, and the ith tap is at location ''taps[i]''.

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