Description
Technical field
The present invention relates to EDA (Electronic Design Automation, electric design automation) verification technique necks
Domain is specifically related to a kind of reusable emulation component and method integrated for simulated environment.
Background technique
The simulation stage of chip is probably divided into unit simulation stage, integrated emulation stage and system emulation stage.Unit is imitative
Really acting on is emulation to single design module, the effect of integrated emulation be to by individually design it is module integrated at chip
The emulation of a subsystem, and the effect of system emulation is the emulation to entire chip.Each simulation stage has corresponding emulation
Environment, and be the relationship stacked in fact between them.That is, system emulation environment is by multiple simulation environment collection
At, simulation environment is integrated by multiple unit simulated environment.Simulated environment is built by several emulation components,
No matter unit environments are integrated into the integration environment, or the integration environment is integrated into system environments, process is consistent, greatly
It causes as shown in Figure 1, since DUT_0 (Design Under Test, tested object) and DUT_1 are merged into for new DUT,
The interface on the left of interface and DUT_1 on the right side of DUT_0 becomes the internal interface of new DUT, therefore it may only be necessary to use env_0
Gen_0 (generator, device of giving out a contract for a project) component and drv_0 (driver, driver) group in (environment, simulated environment)
Part and mnt_1 (monitor, monitor) component in env_1 and scb_1 (scoreboard, scoreboard, it can be understood as
Comparator) component, the connection relationship between component is then re-established, new env is formed.
However, the simulated environment really in chip project is more much more complex than this, there are more components, more lead to
Road exchanges situation between even having access, and the integrated expense of simulated environment is increasing.In project process shorter and shorter today,
Leave that the time that simulated environment is built is fewer and fewer for, this requires simulated environment, and the imitative of next stage can be integrated into the smallest expense
In true environment.
Original way is the emulation component used will to be needed to pick out when simulated environment integrates, and is then taken again
Simulated environment is built, this way does not obviously adapt to present project demands.Now, popular verification method, such as VMM
(Verification Methodology Manual, verification methodology handbook), UVM (Universal Verification
Methodology, generic validation methodology), the integrated method of simulated environment is also given, but still has following disadvantage:
One, integrated object is emulation component, rather than therefore entire environment still needs when environment integrated
Many work are done, expense is bigger.
Two, when simulated environment integrates, as shown in Figure 1, it is idle for having many components in fact, or emulation ring
There are many accesses in border, and when only needing to emulate some access, other accesses are also idle.Present method can only protect
These idle components are demonstrate,proved not run, but these components still can be created, and these components are once created and will disappear
Consumption emulation memory, these memory consumptions are unobvious when chip-scale is smaller, but when chip-scale is bigger
It waits, these memory consumptions will be apparent upon.
Three, when simulated environment integrates, current verification method not can solve that there are when access exchange
As a result the problem of automatic comparison.
In short, existing simulated environment integrated approach is all unable to satisfy in terms of simplification, runnability and flexibility
The integrated demand of present simulated environment.
