SDF Backannotation

Syntax:

TURNOFF_DELAY = FROM_FILE | MINIMUM | MAXIMUM | AVERAGE ;

Example:

TURNOFF_DELAY=FROM_FILE;

modulemap_command:

Redirects the delay object of IOPATH or TIMINGCHECK SDF

statements for all instances of a specified module type to a different

module path or timing check object in the same or lower scope.

Syntax:

MODULE verilog_id { list_of_module_mappings } ;

Here, verilog_id is the name of a specific type of module (not

instance name) specified in the corresponding Verilog description.

list_of_module_mappings:

mtm_command | scale_command | map_inner_command

The mtm and scale commands are as defined earlier. Note that using

these commands as arguments for the module_map_command

affects only the IOPATH, DEVICE, and TIMINGCHECK information

annotated to a specific type of module.

Syntax:

MAP_INNER = verilog_id ;

| systchk = ADD { list_of_systchk }

| systchk = OVERRIDE { list_of_systchk }

| systchk = IGNORE ;

| path_declaration = ADD { list_of_path_declaration }

| path_declaration = OVERRIDE { list_of_path_declaration }
