Altera DesignWare FLEX 6000, FLEX 8000 & FLEX 10K Synthetic Libraries
The Altera® DesignWare interface for the FLEX® 6000, FLEX 8000, and FLEX 10K device families provides accurate area and timing prediction for designs that have been synthesized by the Synopsys design tools and targeted for FLEX devices. Altera's DesignWare interface also ensures that the area and timing information closely matches the final FLEX device implementation generated by the MAX+PLUS® II Compiler. The DesignWare interface synthesizes FLEX 6000, FLEX 8000 and FLEX 10K designs by operator inference. This interface supports bus widths of up to 32 bits, except adder functions, which support bus widths of up to 64 bits.
The Altera DesignWare interface for FLEX devices offers three major advantages to Synopsys designers:
- Automatic access to FLEX carry and cascade chain functions
- Optimal routing of FLEX designs
- Improved area and performance prediction capability in Synopsys tools
Table 1 lists the Altera DesignWare synthetic libraries for FLEX 6000, FLEX 8000, and FLEX 10K devices.
