View source for Instance - Module binding order

'''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:

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