How to draw a serie of polygons with gradually tilted angles

yichun

 There is a row of "a" rectangle objects (about a few thousands) and a row of "b" rectangle objects. The "a" objects has a pitch distance of 0.5 mm, while the "b" object has a pitch distance of 1mm. I want to connect "a" to "b" using a serie of simple polygons (with a width of 0.2mm).    Is there a program to do this, or I have to draw it one by one manually.  Thanks.

a      a       a        a         a       a         a          a         a    ......

 

  

b            b            b            b              b               b                b               b                b                b  ....

  • Hi, Yichuan,

    I assume that you are doing this inside the Cadence Virtuoso tool.   You could create path by command "dbCreatePath(cvid lpp pointList width type)"  (in a script).

    The other way is to create a connection cell, which has wires to hook up one "a" to "b". Then, you could instanciate this connection layout cell as an array/mosaic (match your number of "a" boxes). You have option to flatten this mosaic/array so that all the wires come up to the top level.
