[NAME]
hyp2mat \- convert hyperlynx files to octave/matlab scripts for electromagnetic simulation.
/scripts./
.SH OPTIONS
/Print board summary/
Hyperlynx input files conventionally end in
.BR .hyp
\&.
.I hyp2mat
reads input from file
.IB infile .
If no input file is specified input is read from standard in.
If no output file is specified output is to standard out.
If a syntax error occurs during conversion, error recovery is attempted.
.I hyp2mat
exits with zero status if conversion was succesful and non-zero if not.
The
.BR --verbose
option can be used to list board dimensions.
If only a small region of the board needs to be simulated the
.BR --xmin
.BR --xmax
.BR --ymin
.BR --ymax
.BR --zmin
and
.BR --zmax
options can be used to crop the board to a smaller region.
If not all layers of the board need to be simulated, the
.BR --layers
option may be used to specify layers of interest.
If not all nets of the board need to be simulated, the
.BR --nets
option may be used to specify nets of interest.
The option
.BR --net=?
lists all available nets.
Circles and arcs are approximated by polygons. By default a circle is approximated by an octagon. If higher accuracy is needed, set
.BR --arc-precision
to the desired precision. This will increase the number of line segments used to draw circular, oval and oblong pads, amongst others.
To simulate a lossy dielectric, copy AddHyperLynxDielectric.m to your project directory and customize.
The
.BR --flood
option floods layers with copper.
The flooded copper respects trace-to-plane clearances.
Copper net name is identical to layer name.
Typical use of
.I hyp2mat
is with simulation packages such as OpenEMS.
[EXAMPLES]
Convert pcb.hyp to pdf:
.nf
hyp2mat -o pcb.pdf pcb.hyp
.ni
Examine original Hyperlynx file:
.nf
hyp2mat -o pcb.pdf --raw pcb.hyp
.ni
Draw arcs with an accuracy of 10 mil or better:
.nf
hyp2mat -o pcb.pdf --arc-precision 0.000254 pcb.hyp
.ni
[NOTES]
Board outlines and copper polygons should not be self-intersecting.
Common causes of syntax errors are unquoted strings, and unassigned component values.
.SS Unquoted strings
.IP "Error:"
.I syntax error, unexpected STRING at 'Logo'
.IP "Source:"
.nf
(? REF=My Logo BOT1 L=Bottom_Layer)
.fi
.IP Cause:
An unquoted string contains a space (' ').
.IP Solution:
Edit the .hyp file and put the string between double quotes:
.nf
(? REF="My Logo BOT1" L=Bottom_Layer)
.fi
.SS Unassigned component values
.IP "Error:"
.I syntax error, unexpected L, expecting FLOAT or STRING at 'L'
.IP "Source:"
.nf
(R REF="R1" VAL= L="Top")
.fi
.IP Cause:
Component has not been assigned a value (VAL=).
.IP Solution:
Edit the .hyp file and assign a value to resistor R1:
.nf
(R REF="R1" VAL=0 L="Top")
.fi
or assign the resistor a value in the schematics editor and re-export to HyperLynx.
