Q: Verilog has many ways to find modules not in the file being directly read: -L, -v, -y, .... There may be more than one module of the same name. What is the order of binding?

The order of searching for modules is:

  1. While parsing:
    1. `uselib
    2. -work (present working library)
    3. -L
    4. -y/-v (their order in an f-file is considered)
  2. While elaborating:
    1. configurations
    2. already resolved module from analysis, ie, order of parsing (above)
