descriptions into Yosys: First the Verilog file for the cell library can be
passed directly to the {\tt show} command using the {\tt -lib <filename>}
option. Secondly it is possible to load cell libraries into the design with
the {\tt read\_verilog -lib <filename>} command. The 2nd method has the great
the {\tt read\_verilog -lib <filename>} command. The 2nd method has the great
advantage that the library only needs to be loaded once and can then be used
in all subsequent calls to the {\tt show} command.

it is a good idea to troubleshoot a circuit in the earliest state in which
a problem can be reproduced. So if, for example, the internal state before calling
the {\tt techmap} command already fails to verify, it is better to troubleshoot
the {\tt techmap} command already fails to verify, it is better to troubleshoot
the coarse-grain version of the circuit before {\tt techmap} than the gate-level
circuit after {\tt techmap}.
