- New DRCS
9 I2 m- T3 m! _5 J3 f: ]8 L- q) MIn VX.2.5 new system design rule checks were created to review system integrity. Rule checks include cross-probing from integrity results to the specific item of interest can be enabled, verification that reference designators are unique in a single board and ensuring that the board connectors and have been placed inside a board outline. Cable declarations are locked and names forwarded to the cable designer insuring that the required information is ready for correct by construction cable design.3 |, a& W; D+ A; C+ m
- Connector Management Enhancements
/ \6 E8 Y* M! B- ~The generic symbol pin order for schematic connector does not always achieve the designers desired results. In VX.2.5, users can now use the library symbol pin order column to easily edit pin numbers and the order. Pin orders can now be easily copied from an Excel spreadsheet and the connectors can be place by the pin numbers alpha-numeric value.2 K. _1 W/ X( v$ G1 ?

In VX.2.5, EDM Collaborate now allows users to view the net class and net topology information in the properties view. Whether you are viewing the schematic or layout, the information is available in properties and when selecting a net./ U9 |0 m* S' x1 ^* ]
Layout
I& g" l @2 L% l: K8 F; F- Semi-trunk routing 9 ~% Y7 h* H# x, z+ @
In VX.2.5, a new capability called Semi Trunk routing has been added to Sketch Planning. This capability allows the user to create a Sketch plan that will only be routed on one end of the plan. By choosing the new command, Route Semi-Trunk, the Sketch plan will be optimized for the end opposite the Route to Dot, and then routed. This can help the user to pre-route inteRFaces that may still require placement or pin and gate swapping optimization. To complete optimization of an FPGA or ASIC, and insure the placement of the interface is complete, the user can easily Reverse the Sketch plan to optimize the other end. 9 n2 W$ V2 n! a$ M4 \0 [

. D4 U: t/ q+ U/ V4 BVX.2.5 brings several new electrical DRC checks. For Signal integrity, a new reference rule for traces vs. specific power net. There is also a new Min/Max routed comp to comp length rule. Additionally, there is a new Adjacent layer routing parallel coupling check as well as a new trace width check in BGA area vs. pin pad width, For Power integrity, there is now a new check for stitching via spacing. For ESD, therre is a new check to ensure that components are aligned and finally, for Safety, there is a new rule that checks the distance between soldermask/silkscreen and any objects. 1 t! f5 S- t D/ }0 V/ [6 j
