Title (EN) REMOVAL OF ACUTE ANGLES IN A DESIGN LAYOUT
(FR) SUPPRESSION D'ANGLES AIGUS DANS UNE TOPOLOGIE DE CONCEPTION DE CIRCUIT
Abstract: front page image
(EN)Some embodiments of the invention provide novel methods for removing acute angles from routes in a design layout (Figure 34). The method selects a route with several segments. It then identifies an acute angle between first and second contiguous segments of the route (Figure 33). The method next inserts a third segment between the first and second segments, where the third segment has an associated shape that fills the acute angle between the first and second segments (Figure 13).
(FR)Dans certains modes de réalisation, l'invention concerne des nouveaux procédés destinés à supprimer des angles aigus de routes dans une topologie de conception de circuit. Ce procédé consiste à sélectionner une route comprenant plusieurs segments, à identifier un angle aigu entre un premier segment et un deuxième segment contigus de cette route, puis à insérer un troisième segment entre le premier segment et le deuxième segment, ce troisième segment présentant une forme associée remplissant l'angle aigu entre lesdits premier et second segments.
