%description
Provides the 'vcd2df' function, which loads a IEEE 1364-1995/2001 VCD
(.vcd) file, specified as a parameter of type string containing exactly a
file path, and returns an R dataframe containing values over time. A VCD
file captures the register values at discrete timepoints from a simulated
trace of execution of a hardware design in Verilog or VHDL. The returned
dataframe contains a row for each register, by name, and a column for each
time point, specified VCD-style using octothorpe-prefixed multiples of the
timescale as strings. The only non-trivial implementation details are that
(1) VCD 'x' and 'z' non-numerical values are encoded as negative value -1
(as otherwise all bit values are positive) and (2) registers with repeated
names in distinct modules are ignored, rather than duplicated, as we
anticipate these registers to have the same values. Read more in arXiv
preprint: 'vcd2df' -- Leveraging Data Science Insights for Hardware
Security Research <doi:10.48550/arXiv.2505.06470>.
