Lattice Semiconductor
If desired, a user-defined clock source can be used instead of CCLK/TCK. You need to specify this clock signal,
and instantiate the STRTUP library element in your design. The example shown below shows the proper syntax of
instantiating the STRTUP library element.
Verilog
VHDL
Bit Stream Compression
The LatticeECP/EC devices support bit stream compression. When the Compression preference is set to ON, the
Lattice design software will generate a compressed version of the bit stream file internally along with an uncom-
pressed bit stream file. The LatticeECP/EC devices will route the compressed bit stream through the decompres-
sion engine when the COMPRESS_CONFIG preference is set to ON. The COMPRESS_CONFIG preference
defaults to OFF. It is possible for the compressed bit stream to be larger than the uncompressed bit stream.
