The Partition Merge folder contains reports displaying the results of the partition merge portion of incremental synthesis.

Partition Merge Summary Report

  • Total DLLs shows the total number ofdelay-locked loop (DLL) Definitionused.

Partition Merge Netlist Types Used Report

Reports netlist-type information generated during partition merging for all entities designated as partitions including:

  • Partition Name shows the user-assigned name for the partition.
  • Partition Type shows whether or not the partition was User Created.
  • Netlist Type Used shows which type of netlist was used (Post-Synthesis Netlist | Post-Fit Netlist | Import Netlist | Post-Fit (Import Based) Netlist).
  • Netlist Type Requested shows which type of netlist (Post-Synthesis Netlist | Post-Fit Netlist | Import Netlist | Post-Fit (Import Based) Netlist) was requested.
  • Partition Contents shows the name of the highest level entity used in a partition.

Partition Merge Rapid Recompile Summary Report

Summarizes how much logic Rapid Recompile was able to preserve on a per partition basis. The following are descriptions of each column:

  • Partition Name shows the user-assigned name for the partition.
  • Rapid Recompile Status shows whether Rapid Recompile has engaged or disengaged for the respective partitions. Rapid Recompile can disengage because the design change is too large to justify running Rapid Recompile.
  • Netlist Preservation Requested specifies the number of nodes in the post-synthesis netlist which are unchanged from a previous Analysis and Synthesis. This is done after a netlist comparison of the current and previous post-synthesis netlists.
  • Netlist Preservation Achieved specifies the number of post-fit nodes after merging the previous post-fit and current post-synthesis netlists to achieve a Rapid Recompile hybrid netlist. The preservation ratio reported in this column is often smaller than Netlist Preservation Requested.
  • Notes specifies why Rapid Recompile disengaged for a partition.

Partition Merge Partition Pin Processing Report

Shows the name, partition, type, location, and status of pins in the specified partition.

Partition Merge Partition Statistics Report

Summarizes partition merge statistics for resources including logic utilization, clock control blocks, adaptive lookup tables (ALUTs) usage, logic registers, DSP Blocks, registers, adaptive logic module (Adaptive Logic Module (ALM) Definition) utilization, logic array block (Logic Array Block (LAB) Definition) utilization, multiplier block Definition, I/O pins, virtual pins Definition, I/O pins, virtual pins Definition, connections, partition interface, congestion, port connectivity and registered ports.

Partition Merge Resource Usage Summary Report

Summarizes the utilization of resources for a design targeting a supported device (Arria® series, Cyclone® series, and Stratix® series) family.

Partition Merge DSP Block Report

Reports information about the usage and availability of DSP block Definition. This section is omitted if the design does not include DSP blocks.

The report displays the following information:

  • Statistic shows the operating mode of the DSP blocks.
  • Number-Used shows the number of each type of DSP block used in the device.
  • Available per Block shows the number of each type of function available in each DSP block.
  • Maximum Available shows the maximum number of DSP blocks available in the design.

Partition Merge Messages

Reports messages generated during Partition Merge for the current compilation. Partition merging generates info, warning, and error messages that report conditions observed during the Partition Merge process.
