You will need EDA (Electronic Design Automation) tools like Synopsys VCS or Cadence NC-Verilog to simulate the RTL.
Look for the Sun SPARC Enterprise T5120 or T5220 . opensparc t2 buy
These servers house the UltraSPARC T2, which features 8 cores and up to 64 concurrent threads. You will need EDA (Electronic Design Automation) tools
There are ongoing community efforts to import the OpenSPARC T2 core into LiteX , which simplifies building a System-on-Chip (SoC) around the processor. opensparc t2 buy
To acquire or use the "useful pieces" of this technology today, you have three primary paths: 1. Buying Physical Hardware (UltraSPARC T2)
If you need the actual silicon, you must look for legacy Sun Enterprise servers on the secondary market (e.g., eBay). These systems are the only way to run the hardware natively.
