+<p>The <tt class="docutils literal">MBK_TO_RDS_SEGMENT</tt> table control the way segments are translated into

+Segments are defined by their axis (source &amp; target points) and their width.
+The geometrical transformations are described according to that model.
+Obviously, they are either horizontal or vertical.</p>
+<p>The translation method of a symbolic segment is as follow:</p>
+<ol class="arabic">
+<li><p class="first">The segment is translated into one or more physical rectangles.
+The generated rectangles depends on the tool which is actually
+using <span class="sc">rds</span> and the flag for the considered real layer.
+For instance, real layers flagged with <tt class="docutils literal">DRC</tt> will be generated
+for <tt class="docutils literal">s2r</tt> (for the <tt class="docutils literal">cif</tt> or <tt class="docutils literal">gds</tt>) and <tt class="docutils literal">druc</tt>, but will not
+be shown under <tt class="docutils literal">graal</tt>.</p>
+</li>
+<li><p class="first">Translation into one real layer. <em>First</em> the source &amp; target coordinates and width
+of the symbolic segment are multiplied by the <tt class="docutils literal">LAMBDA</tt> value to obtain a real
+segment. <em>Then</em> one of the <tt class="docutils literal">VW</tt>, <tt class="docutils literal">LCW</tt> or <tt class="docutils literal">RCW</tt> transformation is applied to
+that segment to get the final real rectangle.</p>
+<ul>
+<li><p class="first"><tt class="docutils literal">VW</tt> for Variable Width, expand the real layer staying centered from the

+Introduction
+============
+
+
+The RDS file control how a symbolic layout is transformed into it's real
+conterpart.
+
+.. note:: **Unit used inside the RDS file:** all units are expressed in micrometers.
+
+Alliance tools relying on the RDS file, and what layers are active for them:

+Physical Grid & Lambda Value
+============================
+
+RDS file: ::
+
+    DEFINE  PHYSICAL_GRID  0.005
+    DEFINE  LAMBDA         0.09
+
+Tells that the physical grid (founder grid) step is 0.005µm and the lambda has
+a value of 0.09µm. That is, one lambda is 18 grid steps.
+
+We can distinguish two kind of |RDS| files: 
+
+* The *1µm* kind, odd segment widths and coordinates are allowed, but the ``LAMBDA``
+  value **must** represent an *even* number of foundry grid step.
+* The *2µm* kind, segments widths and coordinates must all be even. And in that case
+  the ``LAMBDA`` value can be any multiple of the foundry grid.
+
+
+The |MBK_TO_RDS_SEGMENT| table
+==============================
+
+The |MBK_TO_RDS_SEGMENT| table control the way segments are translated into
+real rectangles. Be aware that we are translating *segments* and not *rectangles*.
+Segments are defined by their axis (source & target points) and their width.
+The geometrical transformations are described according to that model.
+Obviously, they are either horizontal or vertical.
+
+The translation method of a symbolic segment is as follow:
+
+1. The segment is translated into one or more physical rectangles.
+   The generated rectangles depends on the tool which is actually
+   using |RDS| and the flag for the considered real layer.
+   For instance, real layers flagged with |DRC| will be generated
+   for |s2r| (for the |cif| or |gds|) and |druc|, but will not
+   be shown under |graal|.
+
+2. Translation into one real layer. *First* the source & target coordinates and width
+   of the symbolic segment are multiplied by the ``LAMBDA`` value to obtain a real
+   segment. *Then* one of the |VW|, |LCW| or |RCW| transformation is applied to
+   that segment to get the final real rectangle.
+
+   * |VW| for Variable Width, expand the real layer staying centered from the
+     original one. In those rules, the third number is not used, it is only here
+     to make the life easier for the parser...
+
+     |RDS_VW|
+
+   * |LCW| or |RCW| for Left/Right Constant Width, create an off-center rectangle
+     of fixed width relatively to the real segment. Note that the ``SP`` number
+     is the distance *between the edge* of the real segment and the edge of the
+     generated real rectangle (*not* from the axis). It is often zero.
+
+     |RDS_LCW|

+
+:fboxtt:`Case 1` the |ALU1| is translated in exacltly one real rectangle of
+|RDS_ALU1|, both ends are extended by 0.18µm and it's width is increased
+by 0.09µm.
+
+:fboxtt:`Case 2` the |NDIF| will be translated into only one segment
+under |graal|, for symbolic visualization. And into three real rectangles
+for |s2r| and |druc|.
+
+:fboxtt:`Case 3` the |NTRANS|, associated to a transistor is a little bit
+more complex, the generated shapes are different for the extractor |cougar|
+in one hand, and for both |druc| & |s2r| in the other hand.
+
+* For the extractor (|EXT| & |ALL| flags) there will be four rectangles
+  generateds:
+
+  1. The gate (|RDS_GATE|)
+  2. The left diffusion of the transistor (source or drain) (|RDS_NDIF|).
+  3. The right diffusion of the transistor (drain or source) (|RDS_NDIF|).
+  4. The active area (|RDS_ACTIV|).
+
+  As the extractor must kept separate the source and the drain of the transistor,
+  they are generated as two offset rectangles, using the |LCW| and |RCW| directives.
+
+* For |s2r| and |druc| (|DRC| and |ALL|), five rectangles are generateds:
+
+  1. The poly (|RDS_POLY|).
+  2. The gate (|RDS_GATE|).
+  3. The diffusion, as one rectangle that covers both the |LCW| and the |RCW| (|RDS_NDIF|).
+  4. The active area (|RDS_ACTIV|).
+  5. The N implantation (|RDS_NIMP|).
+
+  In the layout send to the foundry, the source & drain are draw as one rectangle
+  across the gate area (the transistor being defined by the intersection of both
+  rectangles).

+
+The |MBK_TO_RDS_VIA| table
+==========================
+
+This table is to translate *default* VIAs into real via. In the symbolic layout
+the default VIA is simply a point and a set of layers. All layers are converted
+in squares shapes centered on the VIA coordinate. The one dimension given is the
+size of the side of that square.
+
+Note that although we are refering to VIAs, which for the purists are between two
+metal layers, this table also describe *contacts*.
+
+Example: ::
+
+    TABLE MBK_TO_RDS_VIA
+
+        CONT_DIF_P RDS_PDIF  0.54 ALL \
+                   RDS_CONT  0.18 ALL \
+                   RDS_ALU1  0.36 ALL \
+                   RDS_ACTIV 0.54 DRC \
+                   RDS_PIMP  0.90 DRC
+
+        CONT_POLY  RDS_POLY  0.54 ALL \
+                   RDS_CONT  0.18 ALL \

+                   RDS_ALU2  0.45 ALL
+
+    END
+
+.. note:: **In CONT_DIF_P** you may see that only three layers will be shown under
+          |graal|, but five will be generated in the |gds| layout.
+
+
+The |MBK_TO_RDS_BIGVIA_HOLE| table
+==================================
+
+In |s2r|, when generating BIGVIAs, the matrix of holes they contains is
+not draw relative to the position of the BIGVIA itself, but on a grid which
+is common througout all the design real layout. This is to allow overlap
+between two BIGVIA without risking the holes matrix to be not exactly overlapping.
+As a consequence, when visualizing the |gds| file, the holes may not be centerend
+inside one individual BIGVIA.
+
+The |MBK_TO_RDS_BIGVIA_HOLE| table define the global hole matrix for the whole
+design. The first number is the individual hole side and the second the grid step
+(center to center).
+
+Example: ::
+
+    TABLE MBK_TO_RDS_BIGVIA_HOLE
+    
+        CONT_VIA   RDS_VIA1 0.27 0.27 ALL
+        CONT_VIA2  RDS_VIA2 0.27 0.27 ALL
+        CONT_VIA3  RDS_VIA3 0.27 0.27 ALL

+The |MBK_TO_RDS_BIGVIA_METAL| table
+===================================
+
+This table describe how the metal part of a BIGVIA is expanded (for the hole
+part, see the previous table |MBK_TO_RDS_BIGVIA_HOLE|). The rule give for each
+metal:
+
+1. The *delta-with* (have to ask Franck).
+2. The *overhang*, the length the real rectangle is expanded on each side from
+   the symbolic rectange.
+
+Example: ::
+
+    TABLE MBK_TO_RDS_BIGVIA_METAL
+    
+        CONT_VIA  RDS_ALU1 0.0 0.09  ALL \
+                  RDS_ALU2 0.0 0.09  ALL

+
+The |MBK_WIRESETTING| table
+===========================
+
+From a strict standpoint this table shouldn't be here but put in a separate
+configuration file, because it contains informations only used by the symbolic
+layout tools (|ocp|, |nero|, |ring|).
+
+This table defines the cell gauge the routing pitch and minimal (symbolic)
+wire width and minimal spacing for the routers. They are patly redundant.
+
+Example: ::
+
+    TABLE MBK_WIRESETTING
+
+        X_GRID             10
+        Y_GRID             10
+        Y_SLICE           100
+        WIDTH_VDD          12
