Chapter 8 AutoCode Sim Cdelay Scheduler

Figure 8-8. Latencies Present in the AutoCode Scheduler

Template Configuration for Enhanced Performance

As mentioned in a previous section, there are drawbacks to re-executing an

ATR task when it is re-triggered before its outputs have been posted, and

to adopting a global timeline enable policy (increased latency). Thus, a

transition diagram is provided in Figure 8-9 can be substituted for that of

Figure 8-6 to obtain the main features of Sim with Cdelay, while retaining

the original AutoCode enable policy (sync immediate on enable). The

original AutoCode retriggering policy can be recaptured by using the STD

for ATR tasks shown in Chapter 4, Managing and Scheduling Applications,

of the AutoCode User Guide, in lieu of Figure 8-7.
