  • IPexpress now supports MIPI D-PHY for XO2/XO3L. IPexpress enables user to quickly create transmit or receive MIPI interfaces. These interfaces can either support both high speed and low power lanes, or to reduce IO, support high speed lane only. Pin/Pad reports more clearly show which IOs are for MIPI to support board design. See technote TN1202, TN1203 for more details on implementing MIPI D-PHY on XO2 and TN1280 & TN1281 for XO3L
  • LSE expanded support for Netlist Analyzer, a tool that allows users to view the pre-synthesis (RTL) and post-synthesis version of their design as a schematic. This feature allows users to preview or review their designs when LSE is chosen
  • LSE expanded support for synthesis attributes such as full_case, parallel_case, syn_enum_encoding, and syn_sharing
  • Clarity Designer expanded support for Virtual VCCIO for DDR memory. Virtual VCCIO improves interface speed by lowering SSO effect. When using Clarity Planner to assign DDR memory pins, the Virtual VCCIOs will be automatically placed in the correct locations within each DQS group for ease of use

  • Adds support for MachXO2 LCMXO2-2000ZE in WLCSP49 package.
  • Lattice Synthesis Engine (LSE) expanded support for the following family of devices:
    • MachXO3L device
    • ECP5 devices (pure HDL designs only)
  • LSE expanded to support Synopsis Design Constraints (SDC) for commonly used timing constraints. This facilitates timing constraint entry for users who preferred to use SDC based timing constraints.
  • LSE expanded to support various Synplify Pro's synthesis attributes. This allows users to migrate existing Synplify Pro based design to LSE with minimal rewriting of attributes.
  • Enhanced the Auto Hold Correction algorithm. With the new algorithm, designs with zero setup timing score are more likely to have their hold violations fixed. Furthermore after hold correction, the setup timing score should remain at zero. This feature helps user by increasing the yield of usable designs.
  • Enhanced handling of HDL attributes and edits in Spreadsheet View. The enhancement follows the rule that constraints entered in LPF override those entered in HDL flow.
  • If Synopsys Design Constraints (SDC) are used for synthesis, they can now be automatically translated to LPF language and used in the MAP/PAR process. The LPF file created to accomplish this is not visible from Diamond but the constraints can be seen from SpreadSheet View (SSV) much like HDL attributes can be seen from SSV. Automatically using SDC in MAP/PAR is the default behavior in new projects, but not in existing projects. This feature is enabled/disabled through the synthesis strategy setting: “Use LPF Created from SDC in Project” (both LSE and Synplify). This feature provides a single entry point for timing constraints and can help manage preferences that must be defined on nets.
  • ECO editor log information persists. This allows users to the the log information after closing and reopening the window.

  • LSE users can now create and edit Synopsys Design Compiler (SDC) synthesis constraints in the new Lattice Design Constraints graphical editor. This editor automatically populates design clock, port and net names and provides real time syntax and semantic checks. It generates an SDC file that can be used with LSE.
  • With this release comes the new Diamond Deployment Tool. It uses an intuitive wizard approach to create the appropriate device programming file in the format required by the user’s deployment method. Diamond Deployment Tool is a standalone tool available as an accessory in the Lattice Diamond environment.
  • With Lattice Diamond 1.4, users can pause, stop and resume per seed, any of the multi-PAR jobs run under Run Manager. They can export the results in a CSV file, and they can also compare run reports of multiple implementations side by side and easily determine the best implementation for their design.
  • Using Run Manager, users can individually control the maximum number of implementations and multi-PAR processes that can be run simultaneously. Parallel processing is only supported on a single computer with a multi-core CPU. Parallel processing across multiple computers is not currently supported.
  • Lattice Diamond will help users migrate their designs to a lower cost device within the same device family while preserving the current package and board layout. This capability has now been extended to all the Lattice device families supported by Lattice Diamond software. Users are provided pin migration information in the Package view and Spreadsheet views, such as incompatible pins. This pin migration information can also be exported to the Pin Layout file.
  • Lattice Diamond 1.4 software now displays in the hierarchy view resources used by each level of design hierarchy following either the synthesis or the map step. Device resources can therefore be displayed as both logical (registers) and physical (slices) elements. This feature helps users quickly understand what parts of their design are using scarce device resources so that they can optimize the design for the targeted device. This information can now also be exported to a text or a CSV file to enable analysis in other tools.
  • With this release, the pin assignment Design Rule Check (DRC) engine has been redesigned and implemented for the LatticeECP3™, MachXO2 and LatticeSC™ device families to provide real-time as well as on-demand DRC during pin assignment and configuration, and a user-friendly report helps identify and correct pin usage issues.
  • Users can now insert an unlimited number of custom columns in Port and/or Pin Assignments tabs of Spreadsheet View. User can use these columns to comment/document per port or pin. The order of the column can be changed via drag and drop. The information can be exported to or imported from a Pin Layout File. It will not be included in LPF files and will not affect the processing.
  • With this release of Reveal, Token Manager was moved from Reveal Inserter to Reveal Analyzer. This allows tokens to be changed without re-inserting debug and resetting the process list. However it doesn’t allow tokens to be defined before running Analyzer.
  • Synopsys® Synplify Pro® for Lattice synthesis tool has been updated, with version F-2011.09L, released in September 2011.

    • In some cases with Lattice Diamond 1.3, the waveform output is not correct when using 3 TUs and having a Max Sequence Depth of Trigger Expression (TE) set to 4.
    • In some cases, when using LatticeECP3 distributed DP RAM, Reveal would fail with a “circuit has too large data_width” error message.
    • The Inserter GUI sometimes reports "Catch unknown exception".

Lattice Diamond 1.3

  • Lattice Diamond 1.3 software provides updated timing and power analysis device information, as well as final production package, bit stream and SSO analysis data based on the actual silicon characterization for the MachXO2 LCMXO2-1200 and LCMXO2-1200U devices.
  • These changes, plus ongoing improvements to the synthesis, MAP and PAR implementation engines, have resulted in an FMax improvement of 5% to 15% on most designs targeted to the LCMXO2 devices.
  • Lattice Diamond 1.3 adds support for a wafer-level package for the LCMXO2-2000U that is needed for very high volume, cost sensitive applications.
  • Lattice Diamond 1.3 software provides device resource utilization for each logical level of the design hierarchy following synthesis, and enables users to make early design decisions about how to structure their design so that they can optimize utilization of the overall device.
  • Designers can add user-defined clock jitter to their design’s clocks while they are performing static timing analysis of these designs. Users control the amount of clock jitter through an extension to the existing Trace timing preferences, and see the analysis results in both the Trace report and the Timing Analysis View.
  • Software provides features to help migrate a design to a lower cost device while preserving the current package and board layout. This capability is available for MachXO2 and LatticeECP3 devices. Users get incompatible pin information in the Package View and Spreadsheet View. This pin migration information can also be exported to the Pin Layout file.
  • Projects can now support complex multi-file test benches and allow multiple design representations for the same design block (such as for synthesis and a different one for simulation).
  • The simulation wizard can automatically determine which files should be set to simulation and pass the correct options to the simulator.
  • The synthesis design constraints flow allows for multiple files (SDC and/or LDC files) that can be managed similar to the back-end preference files (LPF files).
  • Using Reveal Analyzer, users can now download large trace data amounts and configure complex trigger setups more than 10 times faster than previously possible.
  • With Diamond Programmer, users can program the devices from within Diamond in a much easier way than ispVM for the most common steps such as setting up the cable, scanning the board, and direct programming of the device.
  • Users can directly select the active implementation in Run Manager and also control which one of the multi-par runs is used so that the rest of the design flow can be focused on the implementation that provides the best placement and routing run for that design.
  • Lattice Diamond 1.3 supports the Platform Manager devices
  • Users can manage, document and export the information about the package pin out for early pin planning and pin assignment exchange with PCB designers and/or third party tools for pin assignment signoff and design document. Users can get a device's package pin information right from within Diamond
