1 Simulation semantics (a.k.a. event semantics) HDLs use discrete event simulation changes to variables threads enabled enabled threads executed non-deterministically execution of threads more events Combinational thread: 1 or or v n ) v:=e enabled by any change to v1,..., v n Positive edge triggered sequential threads: clk) v:=e enabled by clk changing tot Negative edge triggered sequential threads: clk) v:=e enabled by clk changing tof Mike Gordon 108 / 128
2 Simulation Given a set of threads initial values for variables read or written by threads a sequence of input values (inputs are variables not in LHS of assignments) simulation algorithm a sequence of states Execute until quiescent then advance simulation time Choose an enabled thread Execute the chosen thread Fire event controls to enable new threads Simulation is non-deterministic Mike Gordon 109 / 128
3 Combinational threads in series l1 l in f g 2 h out HDL-like specification: l 1 := f(in) thread T1 1 ) l 2 := g(l 1 ) thread T2 2 ) out := h(l 2 ) thread T3 Suppose in changes toxat simulation time t T1 will become enabled and assignf(x) to l1 if l1 s value changes then T2 will become enabled (still simulation time t) T2 will assigng(f(x)) to l2 if l2 s value changes then T3 will become enabled (still simulation time t) T3 will assignh(g(f(x))) to out simulation quiesces (still simulation time t) Steps at same simulation time happen in δ-time (VHDL jargon) Mike Gordon 110 / 128
4 Semantic gap Designers use HDLs and verify via simulation event semantics Formal verifiers use logic and verify via proof path semantics Problem: do path and simulation semantics agree? Would like: paths = sequences of quiescent simulation states initial state states after one step states after two steps Mike Gordon 111 / 128
5 Sequential threads: alternative simulation semantics in l out clk Consider two Dtypes in series: clk) l := in clk) out := l Ifposedge clk: both threads become enabled race condition Right thread executed first: out gets previous value of l then left thread executed so l gets value input at in Left thread executed first: l gets input value at in then right thread executed so out gets input value at in Mike Gordon 112 / 128
6 Sequential threads: aligning semantics in l out clk If right thread executed first get formal model semantics R(in, l, out)(in, l, out ) = (l = in) (out = l) If left thread executed first get weird semantics R(in, l, out)(in, l, out ) = (l = in) (out = in) How to ensure formal model semantics? Method 1: use non-blocking assignments: clk) l <= in; clk) out <= l; non-blocking assignments (<=) in Verilog RHS of all non-blocking assignments first computed assignments done at end of simulation cycle Method 2: make simulation cycle VHDL-like Mike Gordon 113 / 128
7 Verilog versus VHDL simulation cycles Verilog-like simulation cycle: Execute until quiescent then advance simulation time Choose an enabled thread Execute the chosen thread Fire event controls to enable new threads VHDL-like simulation cycle: Execute until quiescent then advance simulation time Execute all enabled threads in parallel Fire event controls to enable new threads Mike Gordon 114 / 128
8 VHDL event semantics in clk l out Recall HDL: clk) l := in clk) out := l Ifposedge clk: both threads become enabled VHDL semantics: both threads executed in parallel out gets previous value of l in parallel l gets value input at in Now no race Event semantics matches path semantics Mike Gordon 115 / 128
9 Another example: combinational + sequential in XOR l out clk Exercise: Do VHDL and Verilog event semantics agree? Ignoring race if input does change at clock edge in real world might get meta-stability problems also in previous example need analogue simulation (e.g. using SPICE) Mike Gordon (Circuit from: / 128
10 Summary of dynamic versus static semantics Simulation (event) semantics different from path semantics No standard event semantics (Verilog versus VHDL) Verilog: need non-blocking assignments VHDL semantics closer path semantics Simulation runs generate finite sequences better fit with LTL than CTL Mike Gordon 117 / 128
