Rexsir provides a high quality and a high density automatic routing capability at the level equal to manual routing that an experienced designer can achieve.

Alpha-SX Rexsir is the automatic, highly dense router that employs the shape based routing. Interactive operation is possible from the Alpha-SX and the automation of the routing inside and between the blocks such as memories and Bipolars and ASICs are strongly supported.
By employing the push-aside oriented rip-up retry methodology and smoothing function (the function that optimizes the routing course), the routing result with the quality as high as the manual routing can be achieved.
Also, the optimum layout can be promised within the shortest TAT by employing the option tools of Alpha-SX extensively for device, block editing, compaction, and verification.

Automatic router with highest quality and density for Memory, LCD driver, Analog, employing the shape-based push-aside, rip-up retry function

Routing With High Density And Quality

Highly dense routing with the high quality most suitable for IC layout will be promised by employing the features of shape-based routing method extensively.

Interactive Operability

Automatic routing can be done even for the specific nets. Also manual and automatic incremental routing can be executed by either excluding or including the already routed elements.

Design Integrity

Rexsir shares the rule file and data base with Alpha-SX. TAT will be extensively reduced for the layout by employing the rich editing functions of Rexsir and Alpha-SX (such as Device, Block editing) and related tools (Proton, Laplace, Amper)

Compatible For Various Types Of Device, Cell Models

Rexsir is totally compatible for various types of device, cell models such as memories, LCD drivers, analog devices.
○ MOS/Bipolar device
○ MOS/Bipolar block (Frame port and over cell port)
○ Standard cell (Frame port and over cell port)

Interactive Editor

Rexsir provides with the interactive control of the rich routing functions as options. Semi automatic design environment is prepared to reflect designer's idea easily such as the pre-assigned input of bus routing and the routing of unconnected nets.

Compliance For Various Design Constraint
