99 // Note regarding SVAs below:
100 //
101 // 1) Without the sampled rst_ni pre-condition, this may cause false assertion failures right after
102 // a reset release, since the "disable iff" condition with the rst_ni is sampled in the "observed"
103 // SV scheduler region after all assignments have been evaluated (see also LRM section 16.12, page
104 // 423). This is a simulation artifact due to reset synchronization in RTL, which releases rst_ni
105 // on the active clock edge. This causes the assertion to evaluate although the reset was actually
106 // 0 when entering this simulation cycle.
107 //
108 // 2) Similarly to 1) there can be sampling mismatches of the lc_en_i signal since that signal may
109 // originate from a different clock domain. I.e., in cases where the lc_en_i signal changes exactly
110 // at the same time that the clk_i signal rises, the SVA will not pick up that change in that clock
111 // cycle, whereas RTL will because SVAs sample values in the "preponed" region. To that end we make
112 // use of an RTL helper variable to sample the lc_en_i signal, hence ensuring that there are no
113 // sampling mismatches.

101 // 1) Without the sampled rst_ni pre-condition, this may cause false assertion failures right after
102 // a reset release, since the "disable iff" condition with the rst_ni is sampled in the "observed"
103 // SV scheduler region after all assignments have been evaluated (see also LRM section 16.12, page
104 // 423). This is a simulation artifact due to reset synchronization in RTL, which releases rst_ni
105 // on the active clock edge. This causes the assertion to evaluate although the reset was actually
106 // 0 when entering this simulation cycle.
107 //
108 // 2) Similarly to 1) there can be sampling mismatches of the lc_en_i signal since that signal may
109 // originate from a different clock domain. I.e., in cases where the lc_en_i signal changes exactly
110 // at the same time that the clk_i signal rises, the SVA will not pick up that change in that clock
111 // cycle, whereas RTL will because SVAs sample values in the "preponed" region. To that end we make

113 // sampling mismatches.

99 // Note regarding SVAs below:
100 //
101 // 1) Without the sampled rst_ni pre-condition, this may cause false assertion failures right after
102 // a reset release, since the "disable iff" condition with the rst_ni is sampled in the "observed"
103 // SV scheduler region after all assignments have been evaluated (see also LRM section 16.12, page
104 // 423). This is a simulation artifact due to reset synchronization in RTL, which releases rst_ni
105 // on the active clock edge. This causes the assertion to evaluate although the reset was actually
106 // 0 when entering this simulation cycle.
107 //
108 // 2) Similarly to 1) there can be sampling mismatches of the lc_en_i signal since that signal may
109 // originate from a different clock domain. I.e., in cases where the lc_en_i signal changes exactly
110 // at the same time that the clk_i signal rises, the SVA will not pick up that change in that clock
111 // cycle, whereas RTL will because SVAs sample values in the "preponed" region. To that end we make
112 // use of an RTL helper variable to sample the lc_en_i signal, hence ensuring that there are no
113 // sampling mismatches.

99 // Note regarding SVAs below:
100 //
101 // 1) Without the sampled rst_ni pre-condition, this may cause false assertion failures right after
102 // a reset release, since the "disable iff" condition with the rst_ni is sampled in the "observed"
103 // SV scheduler region after all assignments have been evaluated (see also LRM section 16.12, page
104 // 423). This is a simulation artifact due to reset synchronization in RTL, which releases rst_ni
105 // on the active clock edge. This causes the assertion to evaluate although the reset was actually
106 // 0 when entering this simulation cycle.
107 //
108 // 2) Similarly to 1) there can be sampling mismatches of the lc_en_i signal since that signal may
109 // originate from a different clock domain. I.e., in cases where the lc_en_i signal changes exactly
110 // at the same time that the clk_i signal rises, the SVA will not pick up that change in that clock
111 // cycle, whereas RTL will because SVAs sample values in the "preponed" region. To that end we make
112 // use of an RTL helper variable to sample the lc_en_i signal, hence ensuring that there are no
113 // sampling mismatches.

99 // Note regarding SVAs below:
100 //
101 // 1) Without the sampled rst_ni pre-condition, this may cause false assertion failures right after
102 // a reset release, since the "disable iff" condition with the rst_ni is sampled in the "observed"
103 // SV scheduler region after all assignments have been evaluated (see also LRM section 16.12, page
104 // 423). This is a simulation artifact due to reset synchronization in RTL, which releases rst_ni
105 // on the active clock edge. This causes the assertion to evaluate although the reset was actually
106 // 0 when entering this simulation cycle.
107 //
108 // 2) Similarly to 1) there can be sampling mismatches of the lc_en_i signal since that signal may
109 // originate from a different clock domain. I.e., in cases where the lc_en_i signal changes exactly
110 // at the same time that the clk_i signal rises, the SVA will not pick up that change in that clock
111 // cycle, whereas RTL will because SVAs sample values in the "preponed" region. To that end we make
112 // use of an RTL helper variable to sample the lc_en_i signal, hence ensuring that there are no
113 // sampling mismatches.
