+.TH MDS 10.5 UCDS
+.SH NAME
+mds \- kollmorgen symbolic data format
+.SH DESCRIPTION
+.sp
+.PP
+MDS is the symbolic format for the Kollmorgen Pck Division channel router.
+This is an abbreviated description of the format.
+.sp
+.I Introduction
+.PP
+All MDS data is made up of integers, symbols and keywords. All coordinates
+are expressed in mils, i.e., 1/1000 of an inch (just like fizz!). Coordinates
+can be negative or positive and are denoted by matching parentheses of
+the form (X Y). Symbols require quotes around them if
+not made up of numbers, letters, $ or a _.
+.sp
+.I Data types
+.PP
+There are 15 data types identified by their reserved word. The following is
+a list of valid types:
+.sp
+.ta 1.5i
+.nf
+Border Board edges and keepouts
+Check Design rules to check (not required)
+Design Name of the design
+F2 From-to (before routing)
+Fail Failed from-to (after routing)
+File pointer to another file
+Fix Hand routed wire
+Hole Drill hole
+Level Wiring surface (typically only two: COMP and PBSN)
+Net Net
+Panel Board of some type (optional)
+Route Routed from-to with intermediate points at each bend
+Term Termination site for a net (optional)
+Wire Wire path
+Wire_region Routing zone for layers
+.fi
+.Ce
+.sp
+.B Border id coordinates
+.PP
+Borders are closed loops composed by the coordinates and named by a identifier.
+.sp
+.B Check [rule] [-MIN: n] [-ON|-OFF]
+.PP
+Specifies what design rules should be checked by the
+.I repair
+program.
+.sp
+.B Design [name]
+.PP
+Names a design. Strictly optional.
+.sp
+.B F2 netname coordinates [switches]
+.PP
+From-tos are the principal data format of the routing system. They are
+created from nets by F2gen. Intermediate points are specified by
+following the coordinate by a -I or -W. Valid switches include:
+.ta 0.75i,1.5i
+.nf
+ -LEVEL: level
+ level name (or number)
+ -ORDER: cost_function
+ Sets cost function (see section below)
+ -IFL: n
+ number of inflection points; default 9
+ -MIN_FS_END:
+ sets minimum first and last segment length. Default = 0.
+ -MIN_WIRE_END:
+ sets only wire end segment length.
+ -MDR: n
+ manhattan distance ratio (in tenths, default 1.5 = 15)
+ -AXIAL | -ESCAPE | -EITHER | -DIAGONAL
+ Route path direction; Axial is along axes, escape indicates
+ diagonals on ends only.
+ -AWD: n
+ Adjacent Wire Distance
+ -CLW: window
+ -XDW: window
+ CLW checks for coupled length violations within window {n,l}
+ where n is the center to center distance and l is the length.
+ -XOVER: limit
+ Crossover limit
+.fi
+.sp
+.B Fail netname coordinates [switches]
+.PP
+Fails are identical to from-tos except for be called fails.
+See above list of switches.
+.sp
+.B File [filename] [switches]
+.PP
+This include the filename. The switch specifies what kind of file it is.
+.sp
+.B Fix sequence_no [switches] coordinates
+.PP
+Specifies a hand routed net. It is identical to route records (see below).
+The endpoints must agree with the fail it fixes.
+.sp
+.B Hole code [switches] coordinates
+.PP
+Specifies a drilled or LASER'ed hole. The switches are:
+.nf
+ -SIZE: n
+ size of n mils
+ -WIRED | -NOTWIRED
+ dictates if hole can be wired
+ -TOLERENCE: n
+ -LASED -LEVEL: n | -DRILLED
+ if not drilled, only one layer can be specified
+.fi
+.sp
+.B Level level [-F2_DENSITY: n]
+.PP
+Specifies wiring level directly; designs are assumed to be on one level unless
+otherwise told. The optional switch specifies density of routes on the layer.
+.sp
+.B Net [pre_switches]
+or
+.B Net name [pre_switches] coordinates [post_switches]
+.PP
+If the net name is omitted, then the switches are global. The pre_switches
+include all of the from-to switches plus the following:
+.nf
+ -LINK: n
+ Limit of from-tos using this node; default: 2
+ -FIX | -DECOMP
+ Fixes order in from-to list or decomposes it
+ -FIX_START | -NOFIX_START
+ -FIX_END | -NOFIX_END
+ Treat first or last node as if LINK: 1; default: NOFIX
+ -TERM_TO: pool
+ -TERM_END: pool
+ -TERM_WIRE_END: pool
+ -TERM_LIMIT: n
+ -NOTERM
+ Reduces link by 1. Assigns terminator from pool. Default is -NOTERM
+ -ORDER: cost_function
+ Possible cost functions are:
+ AIR_SL - Airline, shortest to longest
+ AIR_LS - Airline, longest to shortest
+ MAN_SL - Manhattan, shortest to longest
+ MAN_LS - Manhattan, longest to shortest
+ X_SL - X, shortest to longest
+ X_LS - X, longest to shortest
+ Y_SL - Y, shortest to longest
+ Y_LS - Y, longest to shortest
+ -BALANCE: cost_function
+ Possible cost functions are:
+ COUNT - by from-to count
+ AIR - by "airline distance"
+ MAN - by "Manhattan metric"
+ X - by X coordinate
+ Y - by Y coordinate
+ -SUPPLY | -SIGNAL
+ -SUPPLY nets are ignored; default is -SIGNAL.
+.fi
+.PP
+The post_switches are:
+.nf
+ -LINK: n
+ -FIX | -DECOMP
+ -TERM_TO: pool
+.fi
+.sp
+.B Panel [name] coordinates [-DESIGN: name]
+.PP
+Defines a coordinate system for translated output data. Strictly optional.
+.sp
+.B Route [sequence_no] [switches] coordinates
+.PP
+If the sequence number and coordinates are
+omitted, then the switches are globally applied.
+Valid switches include:
+.nf
+ -NET: name
+ -LEVEL: level
+ -W_DIA: n
+ Used by wire clearance checks
+ -CLW: window
+ -XDW: window
+ -AWD: n
+ Adjacent Wire Distance (default 0)
+ -PASS: n
+ Set pass number (starts at 1)
+ -XOVER: limit
+ Sets limit to wire crossovers; can be NONE, ONE or TWO.
+.fi
+.sp
+.B Term pool coordinates
+.PP
+Pool together a set of coordinates of terminals given by XY coordinates.
+Typically used by the TERMGEN program to assign terminators automatically.
+Used by ECL freaks.
+.sp
+.B Wire [sequence_no] [switches] coordinates
+.PP
+Just like routes except ...
+.sp
+.B Wire_region [zone] [switches]
+.PP
+Specifies an XY plane where wiring can be done by the router. If the zone
+is omitted then the specification is global. The switches are:
+.nf
+ -LEVEL: level
+ -AWE_WE: n
+ Axial Wire Edge to Wire Edge distance
+ -AWE_HE: n
+ Axial Wire Edge to Hole Edge distance
+ -DWE_WE: n
+ Diagonal Wire Edge to Wire Edge distance
+ -DWE_HE: n
+ Diagonal Wire Edge to Hole Edge distance
+ -W_DIA: n
+ Wire diameter
+ -NSID: n
+ Normal/Segment Intercept Distance.
+ -MAX_HTURN: n
+ Maximum turn angle (in degrees)
+ -DIR: name | -DBECTORY: name
+ Prepend this name to map file output name.

+.sp
+The following is a typical map file for input to Mapgen:
