Counter Tips

• Do not use binary sequence if unnecessary

• Consider higher performance or smaller counter types

  • Examples: LFSR, Pre-scaled, Gray

• Use Pre-Scaling on non-loadable counters to increase speed

  • LSBs toggle quickly

• Use Gray code counters if decoding outputs

  • Glitch free, since one-bit changes per transition

• Consider Linear Feedback Shift Register for speed when terminal count is all that is needed

  • Or when any regular sequence is acceptable (e.g., FIFO)
