  • New architecture editor based on CodeMirror
• User Interface:
  • Several improvements and minor bugs fixed

4.1.x:

• New functionality:
  • CREATOR Remote Lab
  • Dockers for CREATOR
• User Interface:
  • Several improvements and minor bugs fixed

4.0.x:

• New functionality:
  • Integration with real hardware based on RISC-V (ESP32)
  • Possibility to choose the default working architecture
• User Interface:
  • Improved register file visualization
  • Performance improvements (e.g. program execution, data segment loading, etc.)
  • Updating external dependencies (fontawesome v6.2.1, jquery v3.6.3, lodash v4.17.15, and Apexchart)
  • Several minor bugs fixed

3.2.x:

• User Interface:
  • New link to the quick reference guide for instructions in PDF
  • The current assembly code can be shared as a simple link
• Modular design:
  • Simplified pseudo-instruction forms
  • Improved memory detail panel
  • Hardware counter updated to know the number of clock cycles consumed since the last reset

3.1.x:

• User Interface:
  • Example set added
  • The Instruction help width can now be configured from the configuration modal
  • Clarification on the initial CREATOR page
  • Better responsive behavior on different screen sizes
  • Power consumption added
• Modular design:
  • Interface based on Vue components for all UI elements in CREATOR
  • Simulated main memory reworked
  • Architecture improved

3.0.x:

• Several minor RISC-V improvements
• More modular design:
  • Initial user interface based on Vue components
  • Improved modular design on the execution engine
• Improved instruction definitions:
  • New CREATOR API for instruction definitions
  • Support for helping on checking Stack Calling Conventions
    • Checking saved registers on the stack are restored
    • Colored stack
    • SP and FP pointers are shown on the memory stack detail panel

2.1.x:

• RISC-V supported (Thanks to Lucas Elvira Martín @luck5941)
• CREATOR accessibility improved up to WCAG 2.0 (Level AAA)
• Command line version of CREATOR:
  • Help:
    • ./creator.sh -h
  • Example: creator compiles and executes the example2.txt, showing the final state:
    • ./creator.sh -a architecture/MIPS-32.json -s examples/MIPS/example2.txt
  • Example: save final state into 'output.txt' file:
    • ./creator.sh -a ./architecture/MIPS-32.json -s ./examples/MIPS/example2.txt -o min > output.txt
  • Example: compare the final state and the state saved on 'output.txt' file:
    • ./creator.sh -a ./architecture/MIPS-32.json -s ./examples/MIPS/example2.txt -o min -r output.txt
• Creator now accepts three GET values:
  • Preload the MIPS architecture:
    • https://creatorsim.github.io/creator/?architecture=MIPS-32
  • Preload example 'e3' from example set 'uc3m-ec':
    • https://creatorsim.github.io/creator/?example_set=uc3m-ec&example=e3
• Bootstrap-vue upgraded up to v2.15.0
