ARM®︎ Cortex®︎-A53 MPCore Processor rev. r0p4 lint errors

We are integrating in an ASIC design an ARM® Cortex® -A53 MPCore Processor rev. r0p4, then we are running VCSpyglass and we are getting some linting errors. I have listed below the most relevant.

ConcatUnsizedNumbers-ML

Module: ca53scu_cpuslv

File: a53x1_CORTEXA53/RTL/ca53scu_cpuslv.v

Line number: 2722

RTL expression: CPU_NUM

Concatenations cannot have unsized number 'CPU_NUM' [Hierarchy: ':xxx...cpuslv.g_reqbuf ']

ImproperRangeIndex-ML

Module:gic500_icb_rd0_ramaccess

File: a53x1_GIC500/RTL/gic500_icb_rd0_ramaccess.v

Line number: 267

RTL expression: [axis_rd0_rd_id_bounded +:4]

Concatenations cannot have unsized number 'CPU_NUM' [Hierarchy: ':xxx...cpuslv.g_reqbuf ']

SelfAssignment-ML

Module: ca53dpu_dec_late_neon

File: a53x1_CORTEXA53/RTL/ca53dpu_dec_late_neon.v

Line number: 4185

RTL expression: tmp_pipectl[`CA53_FP_PIPECTL_RMODE_BITS] = tmp_pipectl[`CA53_FP_PIPECTL_RMODE_BITS] |

Same operand 'tmp_pipectl[((((... 1) + 1) + 5))] ' used on both sides of an assignment

SignedUnsignedExpr-ML

Module: gic500_icb_rd0_cpu

File: a53x1_GIC500/RTL/gic500_defs.v

Line number: 243

RTL expression: cpu_num = cpu_min(aff1) + aff0;

Unsigned expression 'aff0' used with signed expression 'cpu_min(aff1)'

W216

Module: gic500_icb_rd0_cpu

File: a53x1_GIC500/RTL/gic500_defs.v

Line number: 244

RTL expression: aff_to_cpu_num = cpu_num[LOG2_NUM_CPUS_MSB:0];

Inappropriate range select for int_part_sel variable: "cpu_num[LOG2_NUM_CPUS_MSB:0] "

W241

Module: gic500_axis_addrdec

File: a53x1_GIC500/RTL/gic500_axis_addrdec.v

Line number: 75

RTL expression: output wire p0_its_translate_req,

Output 'p0_its_translate_req' is never set.[Hierarchy: ':a53x1_top_22fdx...500_axis_addrdec']

W416

Module: ca53dpu_mac

File: a53x1_CORTEXA53/RTL/ca53dpu_mac.v

Line number: 541

RTL expression: adif = ~dif[8] ? dif[7:0] : b - a; (LHS: 8, RHS: 9)

Return type width '8' is less than return value width '9' in function 'adif' [Hierarchy: ':a53x1_top_22fdx...ca53dpu_mac:adif']

W468

Module: ca53governor_cpu_timers

File: a53x1_CORTEXA53/RTL/ca53governor_cpu_timers.v

Line number: 558

RTL expression: assign nxt_pcnt_sample_bit = cp_cntpct[cnthctl_evnti] ^ cnthctl_evntdir;

Variable/Signal 'cp_cntpct' is indexed by 'cnthctl_evnti' which cannot index the full range of this vector.[Hierarchy: ':a53x1_top_22fdx...ernor_cpu_timers']

W415

Module: ca53scu_l1d_tagrams

File: a53x1_CORTEXA53/RTL/ca53scu_l1d_tagrams.v

Line number: 392

RTL expression: assign l1d_tagram_cpu3_way1_rdata_o = {(CPU_CACHE_PROTECTION ? 40 : 33){1'b0}};

Signal 'a53x1_top_22fdxp..._way1_rdata[1:0]' has multiple simultaneous drivers

Could these lint errors be waived? 

Thank you in advance.

Jose Antonio.
