end

#branch_to(label) ⇒ Object Also known as: branch

Branch execution to the given point.

This generates a new vector with a jump instruction to a given label. This method will generate an additional vector.

Examples

$tester.branch_to("something_significant")



637
638
639
 
# File 'lib/origen_testers/igxl_based_tester/base.rb', line 637

def branch_to(label)
  cycle(microcode: "jump #{label}")
end

#call_match ⇒ Object

Call a match loop.

Normally you would put your match loop in a global subs pattern, then you can call it via this method. This method automatically syncs match loop naming with the match generation flow, no arguments required.

This is an IGXLBasedTester specific API.

Examples

$tester.cycle
$tester.call_match  # Calls the match loop, or the first entry point if you have multiple
$tester.cycle
$tester.call_match  # Calls the match loop, or the second entry point if you have multiple



596
597
598
599
600
 
# File 'lib/origen_testers/igxl_based_tester/base.rb', line 596

def call_match
  @match_counter = @match_counter || 0
  call_subroutine("match_done_#{@match_counter}")
  @match_counter += 1 unless @match_counter == (@match_entries || 1) - 1
end

#call_subroutine(name, options = {}) ⇒ Object

Call a subroutine.

This method applies a call subroutine opcode to the previous vector, it does not generate a new vector.

Subroutines should always be called through this method as it ensures a running log of called subroutines is maintained and which then gets output in the pattern header to import the right dependencies.

An offset option is available to make the call on earlier vectors.

Examples

$tester.call_subroutine("mysub")
$tester.call_subroutine("my_other_sub", :offset => -1)

  }.merge(options)
  unless @inhibit_vectors
    called_subroutines << name.to_s.chomp unless called_subroutines.include?(name.to_s.chomp) || @inhibit_vectors
    update_vector microcode: "call #{name}", offset: options[:offset]
  end
end

#called_subroutines ⇒ Object

Returns an array of subroutines called while generating the current pattern

#match(pin, state, timeout, options = {}) ⇒ Object

Generates a match loop on up to two pins.

This method is not really intended to be called directly, rather you should call via Tester#wait e.g. $tester.wait(:match => true).

The timeout should be provided in cycles, however when called via the wait method the time-based helpers (time_in_us, etc) will be converted to cycles for you. The following options are available to tailor the match loop behavior, defaults in parenthesis:

  • :pin - The pin object to match on (required)

  • :state - The pin state to match on, :low or :high (required)

  • :pin2 (nil) - Optionally supply a second pin to match on

  • :state2 (nil) - State for the second pin (required if :pin2 is supplied)

  • :check_for_fails (false) - Flushes the pipeline and handshakes with the tester (passing readcode 100) prior to the match (to allow binout of fails encountered before the match)

  • :force_fail_on_timeout (true) - Force a vector mis-compare if the match loop times out

  • :on_timeout_goto (“”) - Optionally supply a label to branch to on timeout, by default will continue from the end of the match loop

  • :on_pin_match_goto (“”) - Optionally supply a label to branch to when pin 1 matches, by default will continue from the end of the match loop

  • :on_pin2_match_goto (“”) - Optionally supply a label to branch to when pin 2 matches, by default will continue from the end of the match loop

  • :multiple_entries (false) - Supply an integer to generate multiple entries into the match (each with a unique readcode), this can be useful when debugging patterns with multiple matches

  • :force_fail_on_timeout (true) - force pattern to fail if timeout occurs

  • :global_loops (false) - whether match loop loops should use global labels

  • :manual_stop (false) - whether to use extra cpuB flag to resolve IG-XL v.3.50.xx bug where VBT clears cpuA immediately

    at start of PatFlagFunc instead of at end.  Use will have to manually clear cpuB to resume this pattern.

Examples

$tester.wait(:match => true, :time_in_us => 5000, :pin => $top.pin(:done), :state => :high)

#store(*pins) ⇒ Object Also known as: to_hram, capture

Capture a vector to the tester HRAM.

This method applies a store vector (stv) opcode to the previous vector, note that is does not actually generate a new vector.

Sometimes when generating vectors within a loop you may want to apply a stv opcode retrospectively to a previous vector, passing in an offset option will allow you to do this.

On J750 the pins argument is ignored since the tester only supports whole vector capture.

Examples:

$tester.cycle                # This is the vector you want to capture
$tester.store                # This applies the STV opcode

$tester.cycle                # This one gets stored
$tester.cycle
$tester.cycle
$tester.store(:offset => -2) # Just realized I need to capture that earlier vector

  update_vector microcode: 'stv', offset: options[:offset]
  last_vector(options[:offset]).contains_capture = true unless @inhibit_vectors
end

#store_next_cycle(*pins) ⇒ Object Also known as: store!

Capture the next vector generated to HRAM

This method applies a store vector (stv) opcode to the next vector to be generated, note that is does not actually generate a new vector.

On J750 the pins argument is ignored since the tester only supports whole vector capture.

Examples:

$tester.store_next_cycle
$tester.cycle                # This is the vector that will be captured
