Hello,
I have uploaded a PowerShell script to test LTSpice performance (LTSpiceBenchmarkEricSims.zip).
The test files include the quasi standard test files bjtff.cir, mike2.cir, mux2.cir and more complex test files.
Please run the test and post the results or report problems here. The file Readme.md has more info.
I am specifically interested in Ryzen 9 versus Intel i9/i7 because in preliminary tests the results are very different (up to a factor 10) depending on the test case.
Best regards,
Udo
