MDS(10.5) MDS(10.5) NAME mds - kollmorgen symbolic data format DESCRIPTION MDS is the symbolic format for the Kollmorgen Pck Division channel router. This is an abbreviated description of the format. Introduction All MDS data is made up of integers, symbols and keywords. All coordi- nates 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 _. Data types There are 15 data types identified by their reserved word. The follow- ing is a list of valid types: 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 Border id coordinates Borders are closed loops composed by the coordinates and named by a identifier. Check [rule] [-MIN: n] [-ON|-OFF] Specifies what design rules should be checked by the repair program. Design [name] Names a design. Strictly optional. F2 netname coordinates [switches] From-tos are the principal data format of the routing system. They are created from nets by F2gen. Intermediate points are specified by fol- lowing the coordinate by a -I or -W. Valid switches include: -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 Fail netname coordinates [switches] Fails are identical to from-tos except for be called fails. See above list of switches. File [filename] [switches] This include the filename. The switch specifies what kind of file it is. Fix sequence_no [switches] coordinates Specifies a hand routed net. It is identical to route records (see be- low). The endpoints must agree with the fail it fixes. Hole code [switches] coordinates Specifies a drilled or LASER'ed hole. The switches are: -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 Level level [-F2_DENSITY: n] 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. Net [pre_switches] or Net name [pre_switches] coordinates [post_switches] If the net name is omitted, then the switches are global. The pre_switches include all of the from-to switches plus the following: -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. The post_switches are: -LINK: n -FIX | -DECOMP -TERM_TO: pool Panel [name] coordinates [-DESIGN: name] Defines a coordinate system for translated output data. Strictly op- tional. Route [sequence_no] [switches] coordinates If the sequence number and coordinates are omitted, then the switches are globally applied. Valid switches include: -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. Term pool coordinates Pool together a set of coordinates of terminals given by XY coordi- nates. Typically used by the TERMGEN program to assign terminators au- tomatically. Used by ECL freaks. Wire [sequence_no] [switches] coordinates Just like routes except ... Wire_region [zone] [switches] 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: -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. The following is a typical map file for input to Mapgen: Level COMP Level PBSN -F2_density: 50 Net -balance: air Wire_region A -Level: COMP -Max_Hturn: 135 -NSID: 15 -W_dia: 8 Wire_region A -AWE_WE: 8 -AWE_HE: 15 -DWE_WE: 27 -DWE_HE: 8 Wire_region B -Level: PBSN -Max_Hturn: 135 -NSID: 15 -W_dia: 8 Wire_region B -AWE_WE: 8 -AWE_HE: 15 -DWE_WE: 27 -DWE_HE: 8 UCDS MDS(10.5)
