NAME

        icetime - generate timing estimates

SYNOPSIS

         icetime [OPTIONS] FILE.asc

DESCRIPTION

       Generate timing estimates from a textual bitstream file (such as output from arachne-pnr).

OPTIONS

       -p <pcf_file>
              Specify PCF file to use (needed for correct IO pin names).

       -P <chip_package>
              Specify chip package (needed for correct IO pin names).

       -g <net_index>
              Write  a  graphviz description of the interconnect tree that includes the given net
              to 'icetime_graph.dot'.

       -o <output_file>
              Write verilog netlist to the named file. Use '-' for stdout.

       -r <output_file>
              Write timing report to the named file (instead of stdout).

       -d lp1k|hx1k|lp8k|hx8k
              Select the device type (default = lp variant).

       -m     Enable max_span_hack for conservative timing estimates.

       -i     Only consider interior timing paths (not to/from IOs).

       -t     Print a timing estimate (based on topological timing analysis).

       -T <net_name>
              Print a timing estimate for the specified net.

       -v     Verbose mode (print all interconnect trees).
