Version 0.9.0-1 (Stable)

• Date: 2022-April-3

Sumary

This is a Bug fixed release. It fixed a critical bug that avoided to build circuits if icestudio was installed after March the 28th (2022)

Since 2022-March-28 the package click, used by APIO, has been upgraded to the 8.1. Some deprecated functions in Apio are no longer available so the following error appeared any time a circuit was built:

There are errors in the design...
Error: module 'click'  has no attribute  'get_terminal_size'

This bug has been solved in apio 0.8.0.post1. Icestudio 0.9.0-1 uses this version by default

• The Basic top menu has been moved to Edit/Toolbox. Now it is a moveble panel that can be located anyware
• New Label Finder panel for searching for labels and chaging their names and colors
• The Collection manager is shown on the right by default

Version 0.5.1n200403

Icestudio nightly build (v0.5.1n200403). This version is focused on upgrading core components, fixing bugs, compatibility with OSX Mojave and Catalina and some optimizations, oriented to better handle large designs. To highlight, this version works with nextpnr and supports the ECP5 FPGA family, and it includes the first attempt at a plugin system, including a working serial terminal

• Plugin system in progress. This version includes the first plugin system core. The developer's API is coming, and soon it will be possible to develop plugins to extend Icestudio functionality.

For the moment, the developed plugins help us to define the public API and specifications, providing, along the way, amazing functionalities for users. In this release you can play with a serial terminal embedded in Icestudio - very powerful for testing purposes

• NEXTPNR toolchain and ECP5 READY!. Special thanks to Miodrag Milanović (mmicko) for providing support for nextpnr toolchain in both APIO and Icestudio. Now the ECP5 FPGA family can be used in Icestudio. That is a big step forward!

• New SOCs. It has never been so easy to implement a SOC in an FPGA. Drag and Drop your cores!. Download or clone repositories and use these SOCs as Icestudio blocks:

  • J1A-SWAPFORTH SOC for Icestudio, by Obijuan
  • Z80 SOC for Icestudio
  • RISC-V SOC for Icestudio

• More Collections!. A collection is a group of blocks ready to use. There are a lot of powerful blocks!

  • New blocks in the indispensable Jedi Collection, by Obijuan
  • Coleccion-FPGA-Icestudio: Components used in the Spanish vocational training centers on electronic maintenance by Ion Hernández
  • Collection-stdio: Blocks for Standard Input-Output in different devices, by Obijuan

Version 0.5.1n200331

• Initial support for the serial terminal in Icestudio

Version 0.5.1

This version is focused on upgrading core components, fixing bugs, and some optimizations, oriented to better handle large designs. We hope you enjoy this new version, if you want to know the new features included you can view this video recorded by @Obijuan_cube (in Spanish) (Click on the image to watch it in youtube)

• New SOCs. It has never been so easy to implement a SOC in an FPGA. Introducing the first two blocks to implement RISC-V and Z80 processors! Download or clone and use these SOCs as Icestudio blocks:

  • Z80 SOC for Icestudio
  • RISC-V SOC for Icestudio

• New community blocks. The FPGAwars community has been very active and there are interesting new blocks for Icestudio:

  • Collection-Jedi. New blocks in the indispensable Jedi Collection
  • 16bit SPI Master, by Democrito
  • Write only I2C, by Democrito

• Community News:

  • Axiom: 100+kW Motor Controller: Marcos Chaparro and his team have been finalists in the Hackaday prize 2019, using Icestudio and the FPGA open source toolchain

Version 0.5.0

Wellcome to Fast & Furious, Icestudio version, focused on upgrading its core components, fix bugs, and optimizacion. There are a number of updates in this version that we hope you will like, some of the key highlights include:

• Submodule edition. This version improve the edition capatabilities, including the possibility of editing block contents

• Copy & Paste OR Copy & Clone blocks. Submodule edition affects all blocks of the same types. For example if you have in you design six AND blocks and you edit one, all of them will be changed. This is a very powerfull feature, very useful for maintaing large designs

But, if you copy and clone a block, it will be independent from the original block. Later modifications will only affect to this block (not the others)

When cloning blocks, it is important to change the block information for describing the new features

• Generic blocks. When developing a new Collection, if it very helpfull to use Generic blocks as templates. When placing a Generic block from a collection, it acts as a clone, and you can modify it without doing a copy and clone operation

Generics blocks can be created easily just by adding the prefix Generic-

• Labels. The labels allow us to connect blocks without using wires

• Automatic check for new versions. You will receive notifications when new versions of Icestudio are available

Version 0.4.0
