simulator

delete_simulation_breakpoint

Usage

delete_simulation_breakpoint -breakpoint <breakpoint_name>

Options

-breakpoint <breakpoint_name>: Option to delete a specified breakpoint

Description

Deletes a breakpoint with the specified name.

Example

project_open one_wire

initialize_simulation

# Create breakpoint bp1 which will give warning message when simulation

# time reaches 10ns

create_simulation_breakpoint -breakpoint bp1 -equation "TIME_EQ(10ns)" \

-action "GIVE_WARNING"

# Create breakpoint bp2 which will give info message when in_br has 0 in

# value

create_simulation_breakpoint -breakpoint bp2 -equation \

"EQUAL_TO(HPATH(|one_wire|in_br),BUS(0)))" -action "GIVE_INFO"

# Create breakpoint bp3 which will give error message when both in_br and

# out_br have 1 in value

create_simulation_breakpoint -breakpoint bp3 -equation \

"EQUAL_TO(HPATH(|one_wire|out_br),BUS(1)),EQUAL_TO(HPATH(|one_wire|in_br), \

BUS(1))" -action "GIVE_ERROR"

# Before running simulation, disable bp2

# Therefore it shouldn't break at time=0ns when in_br=0

disable_simulation_breakpoint -breakpoint bp2

# When running simulation for the first 50ns,

# expect to see bp1 breaks at time=10ns

run_simulation -time 50ns

delete_simulation_breakpoint -breakpoint bp1

enable_simulation_breakpoint -breakpoint bp2

# Since bp2 is enabled, expect to see bp2 breaks at time=100ns

# when in_br becomes 0 again

run_simulation -time 60ns

# Run simulation until the end of completion

run_simulation
