< h3 > 1.1 Task vs. Rules< / h3 >
< p > Both as a tribute to < a href = "#id3" > < span class = "problematic" id = "id4" > |Makefile|< / span > < / a > , to avoid ambiguties with < a href = "#id5" > < span class = "problematic" id = "id6" > |DoIt|< / span > < / a > and to remember
that they are task < em > generators< / em > , the classes defined to create tasks for the design

< / div >
< div class = "section" id = "a-warning-about-determinism" >
< h3 > 1.2 A Warning About Determinism< / h3 >
< p > There is a very important execution difference from a < a href = "#id7" > < span class = "problematic" id = "id8" > |Makefile|< / span > < / a > . In a
< a href = "#id9" > < span class = "problematic" id = "id10" > |Makefile|< / span > < / a > each rule command is executed in a a separated process, so
information is effectively passed through files which are written then read
from disk. But in < a href = "#id11" > < span class = "problematic" id = "id12" > |DoIt|< / span > < / a > we are running inside < em > one< / em > < a href = "#id13" > < span class = "problematic" id = "id14" > |Python|< / span > < / a > process, so while
using Coriolis and the < a href = "#id15" > < span class = "problematic" id = "id16" > |Hurricane|< / span > < / a > database, all informations stays < em > in
memory< / em > . Files are driven, but < em > not re-read< / em > as the database will use the datas
already present in memory.< / p >
< p > This is not whitout consequences about determism. Let's look at two different
scenarii.< / p >
< ol class = "arabic" >
< li > < p class = "first" > We run straight from the RTL to the layout, using the rule/task sequence:< / p >
< pre class = "literal-block" >
Yosys => design.blif => blif2vst => design.vst => PnR => design.gds
< / pre >
< p > In this case, while < tt class = "docutils literal" > design.vst< / tt > is written on disk, the < tt class = "docutils literal" > PnR< / tt > stage
will not re-read the < tt class = "docutils literal" > vst< / tt > file and directly access the data in memory.< / p >
< / li >
< li > < p class = "first" > Run in two separated steps, first we create the < tt class = "docutils literal" > vst< / tt > file:< / p >
< pre class = "literal-block" >
Yosys => design.blif => blif2vst => design.vst
< / pre >
< p > Then, we perform the < tt class = "docutils literal" > PnR< / tt > :< / p >
< pre class = "literal-block" >
design.vst => PnR => design.gds
< / pre >
< p > In this case, as the < a href = "#id17" > < span class = "problematic" id = "id18" > |DoIt|< / span > < / a > processess has been restarted between the two
tasks, the < tt class = "docutils literal" > PnR< / tt > stage < em > will< / em > read the < tt class = "docutils literal" > vst< / tt > file.< / p >
< / li >
< / ol >
< p > The determism in < a href = "#id19" > < span class = "problematic" id = "id20" > |Coriolis|< / span > < / a > is ensured through the unique identifiers of the
objects, attributed in creation order. So between thoses two scenarii, the
identifiers will change and so the algorithm results. The differences should
be minor as the identifiers are used as a < em > last ditch< / em > test to sort between
two objects which cost functions are exactly equal, nevertheless, it will
occur.< / p >

< p class = "first admonition-title" > Note< / p >
< p class = "last" > < a href = "#id21" > < span class = "problematic" id = "id22" > |Coriolis|< / span > < / a > is deterministic, meaning that each scenario will always
give the same result. The difference is truly < em > between< / em > scenarii.< / p >
