Hello Dear Readers, Today in this post, I will provide some deep insight about yaml langauge for CAD flow developments with detailed examples. YAML is not a programming language in the same sense as Python, Tcl, C++, or Verilog. It is primarily a human-readable data serialization/configuration language . In semiconductor EDA, that distinction is important because YAML generally describes what a flow should do , while Python/Tcl/Shell and the EDA tools execute the flow . The official YAML specification describes it as a data serialization language designed to be human-friendly and portable across programming languages. For the semiconductor angle, this becomes particularly interesting because YAML can act as a configuration layer between design methodology and EDA implementation . Frameworks such as Hammer explicitly use YAML/JSON configuration and an intermediate representation to standardize information exchanged between design, technology, and tool plugins. 1.

Hello Dear Readers, Today in this post I will provide some basics to advanced ARM's assembly language practice QA part-4, I have used the Keil tool for code writing. Q-1). Write an assembly language program that performs a mode change by modifying the contents of the CPSR. a. The mode you should change to is user mode, and you have to modify the mode field of CPSR by the value of 0x10. b. This assumes that the current mode is a privileged mode such as supervisor mode. Code: ; program which changes the microprocessor mode masking equ 0x1f user_mode equ 0x10 area change, code, readonly entry MRS R0,CPSR; read the status of the microprocessor BIC R0, R0,#masking; apply the masking bit ORR R0,R0,#user_mode ; set the mode user_mode MSR CPSR_C,R0 ; written back with control_field_mask END Output: Q-2). Write an assembly language program that generates S...
