#generate_field(empty_char = @last_empty_char) ⇒ Object Also known as: show

generate_field should not need to be called explicitly. It is called

by other methods when need-be, and is fundamentallyis responsible
for two things:

  1. It fills the .field array with the appropriate symbols/markers.
  2. It concatenates the array elements into printable rows, and prints
     them.

.plot can be called explicitly and accepts string arguments with

or without regex styling. For example:

  $dut.package = :t4240
  $dut.package.plot("ddr_interface") # plots all "ddr interface" groups
  $dut.package.plot("grounds") # adds ground pins to the previously instantiated plot
  $dut.package.plot("d1_mdq37","$") # plots controller 1 mdq 37, and uses $ as a legend marker
  $dut.package.plot("d2_mdq[3-6]0) # plots d2_mdq30, d2_mdq40, d2_md520, and d2_md620

#prepare_plot ⇒ Object

prepare_plot should not need to be called explicitly. It is called

by other methods when need-be, and is fundamentallyis responsible
for two things:

  1. It checks that self.types includes a "BGA" option.
  2. It populates the .field attribute with a multi-dimensional
     array, proportional in size to the package BGA.
