formal and functional verification
In EDA industry a subset of formal verification known as logic equivalence check is used mostly for digital designs although formal techniques are being applied to analog designs and mixed signal circuits as well but BDDs and Kirpke graphs are treated as...
formal verification
Functional verification is usually exhaustive, checking all boundary conditions to get a golden RTL, it is prior to synthesis. It is generally done using a tool that does timing verification such as NCSIM/SimVision and ModelSim.
Formal verifcation tools compare RTL golden...
Means the HDL code can be translated into physical circuits such as shift registers, counters etc. which may or may not be functionally correct.
Most synthesis tools for FPGAs do not support real numbers.
Dynamic means run time, while system is operative.
Partial means part of the resident resources are reprogrammed while other system areas are unaltered.
Hello Gurus,
I wrote a state machine in VHDL and then simulated it using ISE and ModelSim in three different ways within ISE:
A) New Source -> VHDL Test Bench, entered test vectors in the process statements
B) New Source -> Test Bench Waveform, generated a behavioral .vhw file from wave forms...
I have a mismatch in Modelsim behavioral simulations using 1) VHDL
testbench in ISE and 2) manual entry of stimuli.
While the vector inputs are same in time and values in both cases, the
output, however, is different. The manual simulation seems working as
designed but the testbench based...
In the United States typically PCB designers are not college graduates, they have experience and lots of it. Normally the hardware engineer, the one who captures the schematic and designs the system sits with the layout guru about SI and EMC conformity issues. The PCB designer knows the gimmicks...
Re: Job in USA
You may land on a Swedish company's payroll such as Saab Ericsson in the USA.
Such company's always look for their native speakers, however, you may have to change technologies to get such job i.e., you may not exactly find a job that fits your educational/experience profile.
