27 Two main kind of cells can be used as inputs for l2p :
28 First, you can use l2p to print symbolic layout cells. File formats can
29 be .ap or .cp . This is given by an environment variable MBK_IN_PH that
30 gives the appropriate symbolic layout file format.
31 Second, you can use l2p to print real layout cells whose file formats
32 can be .cif or .gds . This is given by an environment variable RDS_IN
33 that gives the appropriate real layout file format.
34 The path to the input file is set up by two environment variables:
35 MBK_WORK_LIB(3) and if not found MBK_CATA_LIB(3). The output of l2p is
36 a PostScript file in the current directory. The drawing size and the
37 paper size can be specified by the user. So, you can split your drawing
38 in as many pages as wanted. The resulting file can be then used on any
39 adequat Postcript printer.
40 l2p will generate in the current directory, either a single file called
41 <cellname>.ps, either several files suffixed by -<x>x<y>.ps, depending
42 on whether you've asked for a monopage plot or for a drawing that will
43 be split on several pages. If you do something like l2p -pages=2x1
44 cell, it will generate two files called cell-1x1.ps, and cell-2x1.ps.
45
47 With no options, l2p generate a 'standard file', with all options off.
48 This is ok for leaf cells, but not for large circuits.
49 -color generates a color PostScript file for use with color inter‐
51 preters. The default value gives a black and white PostCript
52 file.
53 -drawingsize=<width>x<height>
55 specifies the drawing area in centh of inch. By default, wide =
56 725 and height = 1068 for french A4 paper. If the drawing size
57 is bigger than the paper area, then the drawing will be split on
58 several pages.
59 -fA3 The drawing is done on A3 format paper.
61 -fLETTER
63 The drawing is done on LETTER format paper.
64 -fLEGAL
66 The drawing is done on LEGAL format paper.
67 -givebwdict
69 give the Black & White internal PostScript dictionary. See
70 below.
71 -givecolordict
73 This option must be unique on the command line. When used as
74 in 'l2p -givebwdict', l2p then gives on the standard output
75 its Black & White internal Postscript dictionary. A Post‐
76 Script dictionary is a set of mac- ros that will be used during
77 interpretation of your PostScript file. The macros in the
78 internal PostScript dictionnaries of l2p allows you to control
79 which layer to output, how to plot rectangles, and specify
80 the colors of the rectangles. You get the standard diction- nary
81 by a line of the form 'l2p -givecolordict > dict.ps'. You
82 can then edit it, in order to reuse it with l2p, see the '-use‐
83 dict' option below.
84 -help gives you this man page that explains how to use l2p.
86 -noheader
88 prevents the border and various info, as the cellname and the
89 position of the page in the drawing, from being printed.
90 -papersize=<x_low_left>x<y_low_left>x<width>x<height>
92 specifies the paper area in centh of inch. By default,
93 50x50x726x1069 for a4 paper.
94 -pages=<number_of_x_pages>x<number_of_y_pages>
96 specifies the drawing area in pages. It can be useful, instead
97 of having to calculate the size in cenths of inch of the draw‐
98 ing, to give it in numbers of pages. It takes care of the resiz‐
99 ing of the paper and whether there is a header.
100 -tsize=<s>
102 Available sizes:6,8,10,12,14.The default value is 8.
103 -nrname
105 No name at all will be displayed.
106 -ncname
108 The external connector's names won't be displayed.
109 -nrfname
111 The references's names won't be displayed.
112 -niname
114 The instances's names won't be displayed.
115 -nsname
117 The segments's names won't be displayed.
118 -mfeed Manualfeed:if set,informs the printer that it will be fed by the
120 user himself,for each printing .
121 -real uses real file (cif, gds). By default, uses symbolic layout file
123 (ap, cp).
124 -resol=<x>
126 is the resolution of the file in dots per inch (dpi). This value
127 has been introducted to limitate the size of the generated Post‐
128 Script files. Each rectangle whose width and height are smaller
129 than the resolution will not be printed. The default value is
130 72dpi. It should only be changed in one specifical case : when
131 you want to produce a plot of several meter large. Usually, you
132 must provide a PostScript file sized for A4 paper with a much
133 better resolution than 72dpi. You can then increase that value
134 to up to 1000dpi, but be aware that the size of the file will
135 probably be bigger than a 44Mb SyQuest cartridge that is used in
136 PAO for exchanging data files.
137 -rflattencatal
139 flattens the cell to the catalog level. see catal(5) for more
140 details on the use of the catalog file. Be careful, this option
141 requires a lot of memory...
142 -rflattentrans
144 flattens the cell to the transistor level before printing. Be
145 careful, this option requires a lot more memory...
146 -rotate
148 rotate the cell from 90 degree. This is useful if you have a
149 wide cell, and you want to have it printed in landscape mode.
150 -scale=<f.f>
152 forces the cell to be printed with a certain scale (a floating-
153 point number). This is very useful, when you are printing a
154 whole library of cells, and you want all cells to be printed to
155 the same scale.
156 You can find at which scale a cell was printed by looking at the
157 beginning of the file : 'head n1_y-1x1.ps' will show you a Post‐
158 Script comment beginning by '%SCALE=3.78435' for example.
159 -usedict=<filename>
161 The output Postcript file contains a Postcript dictionary of
162 macros.
163 There are two standard dictionnaries used by l2p for black and
164 white or color prints. This allows you to use a PostScript dic‐
165 tionary different from the two internally encoded into l2p. By
166 modifying one of the standard l2p dictionary, you can choose
167 which layer to output, how to fill the rectangles (empty,
168 hashed, filled), which color to choose, ... and lots of other
169 possibilities. The rest of the generated postscript file is
170 mainly orders of drawing rectangles. PostScript is a reverse
171 polish notation language, that is easy to read for simple pro‐
172 grams.
173 If you use this functionality, and think that your dictionnaries
174 are worth it, please mail them to alliance-users@asim.lip6.fr,
175 in order to submit them for inclusion in future version of l2p
176 (Thanks).

194 l2p -color n1_y
195 will create a colored n1_y.ps file in the current directory :
196 the 'standard' way.
197 l2p -real cell
199 will create a cell.ps file in the current directory from
200 cell.cif or cell.gds, depending on the RDS_IN environment vari‐
201 able.
202 l2p -pages=3x2 na2_y

215 You will not be able to generate more than approximativly 30 pages at
216 the same time (because of the FOPEN_MAX of your environment). In this
217 case, see the option that is not implemented yet.
218 The generated PostScript is Level 1 for black& white plots. When you
219 use color, it generates Level 1 with color extensions. It may not run
220 with strict Level 1 interpreters, although it runs here with our Apple
221 Personal LaserWriter, Sun Sparcprinters, and Canon CLC-300-PS. It fol‐
222 lows the Adobe Document Structuring Conventions 1, and as there is a
223 fake bitmap image inside each generated files, you can re-use them in
224 your word-processors, or publishing software, because the PostScript is
225 EPSF-1.2 compliant.
