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).
