Hierarchical presentation techniques for a design tool

In a design tool, a method of presenting information for a design, the method comprising:

• presenting in a Gantt chart first information for a block of a design, the block including a sub-block that includes a number of timing steps, wherein the block is for a top-level loop, wherein the top-level loop includes a nested loop, and wherein the sub-block is for the nested loop;
• and
• presenting second information for the sub-block of the design, wherein timing for the block is presented as independent of the number of timing steps of the sub-block, wherein before the presenting the second information, the first information includes an icon summarizing the second information, wherein the timing for the block is presented as independent of latency of the sub-block, wherein the timing steps of the sub-block are control steps. and wherein each of the block and the sub-block includes an independently numbered set of control steps.

In a design tool, a method comprising:

• displaying in a Gantt chart a top-level schedule for a design that includes one or more loops;
• and
• displaying a first loop schedule for a first loop of the one or more loops, wherein control step timing within the first loop schedule is presented relative to the first loop schedule, wherein before the displaying the first loop schedule the top-level schedule includes an icon summarizing the first loop schedule, and wherein control step timing within the top-level schedule is presented as independent of latency of the first loop schedule.

In a design tool, a method comprising:

• displaying in a Gantt chart a top-level schedule for a design that includes one or more loops;
• and
• displaying a first loop schedule for a first loop of the one or more loops, wherein control step timing within the first loop schedule is presented relative to the first loop schedule and presented as being independent of overall timing of the Gantt chart, and wherein control stet timing within the top-level schedule is presented relative to the top-level schedule.
