• 296 - Lattice Diamond: Does the configuration file (such as an ECP3 bitstream) for SPI flash remain at fixed size regardless the size of&nbsp; the FPGA design?

  The configuration file that is used for an SPI flash(or for JTAG download), remains the same size regardless the resource (such as logic cell) percentage utilization in the FPGA design.

• 3514 - Diamond: Why is there a difference in the bitstream file size with a small logic modification in LatticeECP3?

  The bitstream file size increases even with a small modification. The bitstream comprises both fuse data frames (SRAM configuration bits) and EBR initialization information. Fuse data frame size is fixed for the given device irrespective of how huge ...

• Lattice Radiant: Why is the bitstream file size fixed (ex. Always 1.8Mb) even in small designs for Certus-Pro NX?

  Certus Pro-NX, the BIT file size on simplest design is 1.8MB, while for Crosslink-NX it generates 790KB. Whenever design becomes more condensed (especially more usage of EBRs and LRAMs) bitstream size will increase from that 1.8MB. The bitstream size ...
