Metal Configurable Standard Cells
BaySand’s Metal Configurable Standard Cells (mcCORE) consists of a library of over 500 ASIC compatible standard cell logic functions. Implemented on a sea of gates, the library provides a comprehensive family of the fundamental metal configurable logic functions required to develop the digital logic and on-chip memory required of advanced ASIC, ASSP and SoC devices.
Functionally compatible with standard cell libraries, BaySand’s technology is not FPGA or Structured Logic but standard cell with patented technologies for high density metal configurable circuit routing, multi-Vt device support and multiple drive capability, delivering performance, power, cost, area density and time-to-market advantages over standard cell ASIC.
BaySand’s metal configurable cell library (mcCORE) is built around fine grained transistor level metal configuration (the Base Cell – BC) for all core logic cells. Based on the same transistor size as standard cell with minimum transistors per used logic function, it delivers better or equal performance, power and aerial density compared to standard cell ASIC while delivering on unparalleled flexibility for ECO’s, design and specification modifications, changing market requirements and families of products with only metal layer changes.
BaySand’s MCSC cell libraries are also fully compatible with Industry Standard EDA tools and methodologies such as synthesis, place and route, extraction, clock tree generation, etc. for seamless migration or integration of existing and new designs to BaySand’s technology.
BaySand’s Metal Configurable Standard Cells have been designed with maximum routing capability and flexibility providing highest density routing for rapid closure on place and route, timing closure and minimized number of metal layers required.
Patented MCSC Technology enables metal level selection of circuit drive strength without requiring base layer mask changes. This allows efficient matching of circuit performance to desired device performance with metal only design changes.
Only used logic is powered with no power to unused cells eliminating static power and minimizing overall design power consumption.

MCSC PMA Features
- Modular RX/TX channel + CMU (LC)
- Full-duplex transceivers
- Maximum serial data rates and input reference clocks are dependent on specific selected process node performance
- For serial data rate below 600 Mbps, oversampling is used
- Each RX/TX Channel has 3 mode:
- as data lane
- as TX clock generator (using the RX PLL)
- ref clock input
- TX PLL can be either
- Dynamic reconfiguration of PMA blocks
- Flexible reference clocking
BaySand provides a soft multi-protocol PCS to enable protocol optimization to your design. The design is optimized for power, performance and efficient aerial density for required protocols per design.
The digital PCS design is independent of the PMA. The modular multi-protocol PMA plus soft PCS allows efficient transceiver metal only reconfiguration and reuse.
Combining BaySand’s family of metal configurable digital interface IP’s, with BaySand’s MCSC transceiver technology provides the ultimate in flexibility in multi-product design.
Specific transceiver availability and performance characteristics are process node dependent. For details regarding a specific process node, please refer to MCSC Foundation Technology in the Solutions tab.
