+these need to be converted into +.I fizz +format by +.I "fizz cvt" . +.SS Concepts +Types, signals and chips are identified by name. +Pins are identified by name and number. +A +.I name +is a string of letters, +digits or any of the characters +.BR +-.$/:<=>[]\(ul . +Sometimes, the first character +may not be a digit. +A name may not be longer than 137 characters. +.PP +The physical design +consists of a +.I board +containing +.IR pin-holes . +The description details the positions of the pin-holes and the +position and orientation of the chips. +I/O connectors may beconsidered as chips with unmoveable packages. +.PP +The coordinate system for the board has +.I x +increasing to the right and +.I y +increasing upwards. +The origin is at the lower left corner; +no coordinate should ever be negative. +The circuit board and components mounted on it are described +as rectangles. +They are positioned so that their sides are parallel to one or other +of the axes. +Measurements are integers measuring 0.001 inch. +Coordinates are expressed as pairs of integers separated by +.B / +with +the +.I x +coordinate appearing first. +All rectangular regions are half open; +the upper and right edges are outside the rectangle. +.SS Syntax +The input is a sequence of items. +An item consists of a item-type followed by a number of fields. +Multiple fields are indicated by a trailing +.B { +on the keyword line and terminated by a line containing a single +.B } . +Fields are a keyword followed by the value for that field. +Certain values are spread over multiple lines between +.B {} +as described above. +.PP +It is sometimes necessary to provide a list of +coordinates. +Invariably each coordinate is associated with a numbered object +(say, a pin number). +A one coordinate list consists of the index +number followed by its coordinates as in +.RS +.PP +.B +28 1700/2500 +.RE +A series of equally spaced +and consecutively numbered coordinates can be described by +giving the first and last coordinates and separating the +two with +.B - +as in +.RS +.PP +.B +28 1700/2500 - 30 1900/2000 +.RE +Coordinate 29 is 1800/2250. +If the index numbers are equally spaced but not consecutive +a step size can follow the `\fB-\fR' as in +.RS +.PP +.B +12 2000/7000 -9 147 2000/1000 +.RE +This describes coordinates numbered 12, 21, 30, and so on. +If a letter follows the coordinate specifications, +it specifies the drill to be used for the pinholes. +The known drill types are +.RS +.PD 0 +.TP +.B A +33 +.TP +.B B +34 +.TP +.B C +39 +.TP +.B D +42 +.TP +.B E +50 +.TP +.B F +62 +.TP +.B G +106 +.TP +.B H +107 +.TP +.B I +108 +.TP +.B J +20 +.TP +.B K +110 +.TP +.B L +111 +.TP +.B M +112 +.TP +.B N +113 +.TP +.B O +114 +.TP +.B P +115 +.TP +.B Q +116 +.TP +.B R +117 +.TP +.B S +118 +.TP +.B T +119 +.TP +.B U +100 +.TP +.B V +20 +.TP +.B W +122 +.TP +.B X +123 +.TP +.B Y +124 +.TP +.B Z +125 +.PD +.RE +.SS Items +In the following descriptions, +each item has a sample input defining all possible fields. +Some fields are optional;
